modifications

Enhancements and repairs to our coach.

Sewer hose closure

As you may know, I post about RV modification topics every Monday (“Modification Mondays”). I have a long list of potential topics, some smaller than others, so I thought I’d post some of the shorter ones on Thursdays when we don’t have a lot of exploring topics — Thursday for “Tweak Thursdays” (I do enjoy alliteration!). Here’s the first one, about a nice little tweak.

In the wet bay of our motorhome, there is a large hole in the bottom through which one feeds the sewer hose, so the wet bay door can be closed with the hose connected. That is convenient, but it leaves a sizable gap around the hose, through which rodents and such could enter. I previously used some steel wool to close this gap, which worked well, though tended to rust when it got damp, and was a bit of a hassle.

I recently saw a suggestion on Facebook where someone posted about a custom 3D-printed panel that fitted around the sewer hose, and someone else commented that they used one of these flashings instead:

Pipe flashing

That seemed like a great idea, so I bought one (Amazon link) and installed it by cutting a hole and fitting it around the sewer hose:

Wet bay

I had it around a 2-foot-long hose, so I could disconnect that and pull it up out of the hole for travel days, leaving the flashing around the hose. But that was a bit of a hassle, so I came up with another approach: I got a clear 10” extension pipe, and put the flashing around that:

Sewer pipes

Plus a 45° adapter:

That will let me leave the pipe and flashing in place, and just remove the 45° adapter for travel days. I just installed this yesterday, so we’ll see how well it works!

Replaced shower rain head

Our motorhome has a small shower in the main bathroom, with a somewhat low ceiling. It came with a rain showerhead, in addition to a handheld one. But unfortunately it was a bit short for me (I’m 6’ 1”), so I had to duck when having a shower, and was always banging my head on it. Here’s a picture from when we bought the coach; it was a concern then, but not a dealbreaker:

Shower

So I recently solved that. I got Dillon Massey of DC Plumbing in Red Bay to remove that horrible shower head:

The hole:

And install a new shower head and arm that I bought from Amazon. The rain head comes with an 11” arm, plus I bought a second arm to enable it to be positioned higher:

New shower head and arm

As a bonus, I also got Dillon to add a valve under the half bath sink on the toilet hose, so we can shut it off without having to shut off all of the water (especially useful when sanitizing our water tank):

Anyway, back to the shower; here’s the new arm and shower head installed:

So much nicer! Now I can stand under the rain head without hitting my head. I can’t believe I suffered with that old one for over two years.

MagSafe charger on bedroom wall

I used to plug my iPhone in to a USB cable on my side of our bed, to charge it overnight. But when Apple made the switch from Lightning to USB-C for their iPhones, I needed two cables there. Jenn got a MagSafe charger on her side of the bed, which inspired me to get one for my side.

For my one, I decided to just mount it on the wall (or a wall trim, to be precise), using Command strips (which enable easy removal). Here’s my charger:

MagSafe charger

The power cord for it runs down behind the trim, behind the little box (that holds cough drops), and under the window inside a conduit:

MagSafe charger

The power supply is tucked in a corner:

Then an extension cord goes down the wall (along with the wire for the Spyder panel) and under the bed; this is normally hidden by the bed and pillows:

Wire

The MagSafe charger and Jenn’s chargers are connected to a multi-headed splitter:

Squid

This is it in place under the bed (hard to see amongst all the other wires):

Squid

Plugged into this socket, that used to power the subwoofer, which we don’t use:

On Jenn’s side, she has multiple MagSafe chargers, plus a cable for her iPad:

Chargers

Another look at my new MagSafe charger, next to the Spyder panel:

MagSafe charger

My iPhone on the charger; it attaches magnetically, so seems to levitate on the wall:

Why is it vertically offset? This is why; using Apple’s new StandBy mode, that shows widgets (I use different ones nowadays):

A nice enhancement.

Using a sewer tote tank and macerator pump to dump waste tanks from the back of our truck

What goes in, must go out. As mentioned last week, sometimes we stay at rustic campgrounds or rallies where there are no sewer hookups. No big deal for up to about a week. But if we’re staying longer, we have a tote tank that can be used to empty our black and gray tanks, enabling us to camp as long as we want.

We bought a Camco Rhino 36-Gallon Portable Camper/RV Tote Tank from Amazon:

Tote tank box

They (and RVers generally) recommend getting a tank big enough to fit the capacity of the RV’s waste tanks, but that advice is geared towards smaller RVs — our motorhome has a 70 gallon gray tank and 50 gallon black tank, so we need to take two trips to fully empty each.

The instructions that came with the tank:

I also got a Tote Tank Gauge for it, that indicates when the tank is getting full; important since the capacity is smaller than the tanks in our coach:

Fill gauge

I didn’t bother installing the ladder hook, since we don’t have a ladder on our coach. In the future I might add a bar to our towbar to mount a rack onto. But for now I store the tank in the bed of our truck, wrapped in a cover:

Covered tote tank in truck

Here’s the tote tank (when it was brand new):

Tote tank

It has wheels at the back and front; the front wheels can be steered; I normally don’t attach the handle, though:

Wheel

There is a valve on the side to dump the contents:

Dump valve

And a second valve on top for filling, though this can also be used for dumping by tilting the tank vertically:

Fill valve

I also purchased a macerator pump:

Macerator pump

Normally one would position the tote tank next to the wet bay, and use gravity to fill it from the RV’s tanks, then hook the tank to a tow bar or wheel it manually to the campground dump station.

But I wanted to keep it in the bed of our truck, so I could easily drive it to the dump station. So I use the macerator pump to chop up any solids and pump it all uphill into the truck:

Macerator pump

Another time, I attached the macerator directly to the port (with a clear tube); the downside was getting a little water in the wet bay when disconnecting (if the tank isn’t completely drained):

Maserator attached directly

The tank in the back of the truck:

The hose (only used for this purpose) goes from the macerator to the fill valve on top:

Both the water bladder and the sewer tote fit quite nicely together in the bed of the truck:

The fill gauge rising up as it nears capacity:

Once the tote is full (or the RV’s tanks are empty), I drive the truck to the campground’s dump station, hook up a sewer hose to the side valve, and empty the tank:

Dumping from tank in truck

Much more convenient than dragging the tote behind the truck. And like the water bladder, lets us stay indefinitely even in a campground without a sewer hookup.

Refilling our fresh tank with a water bladder and pump

We usually stay at full-hookup campgrounds, as we enjoy our creature comforts. But occasionally we stay at more rustic campgrounds or rallies where there isn’t a water faucet in our site. If a week or less, we just avoid doing laundry, long showers, and using our rear toilet (as that is a macerating one that uses more water on each flush), and can cope without difficulties.

But if we’re staying longer, we have the ability to refill our fresh water tank via a water bladder and pump.

I bought an Aquatank II water bladder from Amazon, a drinking-water-safe flexible water container with a 60 gallon capacity. It folds up really small for when we don’t need it, and fits in the bed of our truck when in use.

Our fresh tank is 90 gallons, so it takes two loads if totally empty, though I usually do one load when it’s about halfway.

Here it is empty, spread out in the bed of our truck. It has an upper hose fitting for adding water, and a lower hose fitting underneath for draining:

Water bladder

I drive the truck to the potable water supply at the campground, and use a hose to connect it to the water bladder:

Hose from potable water supply

I use a water meter to track how much I’ve added:

Water meter

The water bladder mostly full:

50 gallons:

I then drive back to our campsite, and use an electric pump to get the water into our coach, via the usual filters and water softener as I use for campsite hookups:

Pump

(I also got a drill pump as an emergency backup.)

The electric pump is about 16 PSI:

Gauges

The water bladder during draining:

It takes about an hour to do the full fill and empty cycle, depending on the water pressure at the campground. Definitely not as convenient as a faucet at our site, but when we don’t have one, this solution lets us stay longer without having to worry as much about water usage.

Replacing solar fuse with breaker

As followers of this blog may recall, we had a fuse between our solar panels and the solar controller:

Fuse

I had an issue where that fuse blew a few times, possibly due to our extra solar panels putting out too much power. The most recent time I replaced it with a 30 amp fuse:

Fuse

That didn’t end so well — a few months later, that fuse melted. Perhaps cheap junk, I don’t know; it should just blow, not melt. It set off our smoke detector, so could have been much worse:

Melted fuse

I considered replacing the fuse holder, but figured I needed a better solution. I decided to replace it with a circuit breaker, so if it is over-current again it’ll just pop instead of blow or burn.

I needed a short length of wire to connect it, so went to the nearby Lowes for wire, using 8 gauge wire, the same as used elsewhere in the coach:

Shopping for wire

That was an adventure in itself; the guy who helped us wasn’t familiar with wire cutting, but he figured it out.

Wire

I connected a short length of that wire to the breaker:

Breaker with wire

I then drilled some holes for the wires above the solar controller:

Installing breaker

And reconnected the controller to that wire:

Reconnected controller

Here’s the breaker installed, and preparing to re-mount the controller:

The completed breaker and controller (with the solar pulling in 14.4 amps):

Here’s hoping this solution will prove satisfactory!

Photographic artwork

Our coach came with some generic artwork on a wall in the bedroom. But we wanted to personalize it a bit, so we replaced that with 12 photos of favorite places from our travels, printed on aluminum (so we don’t need to worry about breaking glass).

We laid the prints out on our bed to decide on the arrangement:

Artwork

How many of those places do you recognize? I bet there are a few stumpers. Let me know in the comments which ones you recognize, and which ones you’ve visited. See the end of this post for a full list.

The prints came with metal hangers, which wouldn’t really cut it in a rolling earthquake of a motorhome, so I attached Command Strips to stick them to the wall; these Command Strips come in two parts like velcro, so we’ll be able to swap out the pictures in the future if desired:

A huge improvement, and a nice reminder of some of our favorite places.

New tires

A big expense, but an important one: new tires. Motorhome and truck tires don’t wear out like car tires, but instead age out. Tires can last up to ten years, but the advice is to check them starting at five years, and aim for about seven years to replace them, or sooner if there are signs of cracking.

Our 2017 coach had the original tires, made in 2016, so were about due. And when we recently had our brake seize up, raising the temperature of the tire over the danger zone of 200°F, we decided it was time.

These big tires are over a grand each, and we have six of them, so it isn’t a trivial expense, but good tires are very important for the safety of the coach.

We went to Bay Diesel in Red Bay to get this done:

While there, we also got them to look at our generator, which had misbehaved earlier, but of course was working perfectly while they looked at it:

Engine compartment insulation

The insulation above the engine in our motorhome came loose. Apparently this is a fairly common issue, but not ideal:

I used some aluminum tape to temporarily repair it:

But while in Red Bay we got one of the after-hours vendors, Mark Tedford (662-706-0692), to properly fix it for us.

There is an access panel to the engine compartment in our rear bathroom (yes, the engine is at the back, commonly called a “diesel pusher”):

He removed that to enhance its insulation:

Much nicer. The bathroom floor used to get quite warm after a drive, but it is now much cooler. And now we shouldn’t need to worry about it falling apart.
