Coach Proxy

I bought a Coach Proxy device for our 2017 Tiffin Allegro Bus 40SP coach.

This is hardware and web-based software to remotely control the Spyder coach systems like lights, fans, etc. Everything that can be done from the main touch panel.

It is also obsolete technology that has a new lease of life. It was a commercial product a few years ago, but was discontinued. But many people enjoyed it, so it was released as an open source project, and some people have continued to make hardware for it using off-the-shelf components.

The device I purchased was an example of that; it was made by a guy named David Earnest, housed in a 3D-printed case:

The logic board is actually from a Raspberry Pi 400, with another board to interface with the Spyder network:

I had a spare Spyder connector under the dash, so I mounted the box there:

The software side is a web app powered by that hardware, with controls for the various lights etc. Here is the top of the Interior page of Coach Proxy, with the main lights; the ones with a slider can be dimmed:

Scrolling down, the living room TV lift (that TV raises up in front of a window when wanted), and more lights. At the bottom the MEM ON turns on the lights that were on when the ALL OFF was used:

On to the shade controls; day and night shades on the driver and passenger sides, or all at once:

The Exterior page has lights, locks, and water systems:

The Climate page has fans and heated floors (very nice in cool weather):

A nice thing one can do via Coach Proxy that one can’t do via the touch panel is assign presets, to turn on or off custom sets of lights; I just have a couple so far:

The Status page has tank levels and power stuff:

The Notifications page lets me get a notice when certain conditions occur:

Plus there are a couple more pages for settings, including options to set up remote access, so these controls can be changed when away from the coach via a secure connection.

A very useful device.

Water quick connectors and gauges

I have a history of overly complicated plumbing at our former homestead, and having an RV hasn’t prevented that hobby. But always for good reasons.

To make hooking up our fresh water supply components easier, I have added some hose quick connectors, that clip together very easily:

Quick connectors

The first of these is at the tap, in case I want to disconnect due to sub-freezing temperatures. Following that connector is a two-way splitter, with a hose on one side, and a pressure gauge on the other:

Tap, splitter, gauge

This gauge is useful so I can see the pressure of the water supply (which I note in my campground reviews); the black needle indicates the current pressure, and the red needle indicates the maximum pressure:

Gauge

Here they are at another campsite, with a frost-free tap (lowering the handle not only shuts off the water, but also drains the water out of the vertical pipe, so it doesn’t freeze and burst):

Tap, splitter, gauge

At the other end of that hose is a second splitter, with one side going to a flexible cleanout hose, and the other going to a pressure regulator (set to a maximum of 60 PSI, though not approaching that at this campground), another quick connector, and the water filters:

Splitter, pressure regulator, quick connect

On the other side of the filters is another quick connector (so I can disconnect and put it away on travel days), and another gauge, to check the output water pressure (not very high at this campground):

Quick connect, gauge

Here are a couple of pictures showing both sides of the filters (the orange hose in the background is the “stinky slinky”, i.e. sewer hose, on a ramp for proper drainage):

Filters

View from above

The other end of the aforementioned cleanout hose has a built-in valve, and I added a quick connector:

Qucik connect on hose

That connector has a mate and a valve on the black tank flush port; this port is used to rinse out the black (toilet) tank:

Valve and quick connect

Here is the hose connected and both valves turned on:

Connected and on

When I’m done, I can simply turn off these two valves (and the one back at the splitter), and easily disconnect, without any mess:

Connected and off

Nice improvements.

Ceiling AC filters

In the ceiling of our motorhome are a series of register and return vents for the three ceiling AC units; the air is sucked in on the right side, cooled (or heated), and blown out the left side:

Ceiling vents

Here’s a closer view of one of the intake vents:

Ceiling vent

Looking on the reverse side, you can see that each of them includes a foam filter to catch dust:

These filters need to be cleaned every few months. But we decided to try some replaceable filters from RV Air, that should do a better job than just a thin bit of foam:

A comparison of the new and old filters:

About half of the ceiling vents are a different kind, for some reason:

These ones are attached via a clip in the middle, so need a different style of filter:

We’ll see how these new filters perform; I think they’ll be an improvement.

Emergency labels

An excellent idea from the Tiffin Allegro Bus 2016-2018 Owners group on Facebook: I added labels by the door of our RV with our contact information, and that we have a cat inside, in case there’s an emergency like a fire while we’re away from the coach.

To catch the eye a bit, I bought a red “IN CASE OF EMERGENCY CALL 911” sticker from Amazon, and cut out the first couple of lines:

In case of emergency label

Then used my label maker to print labels with our phone numbers, and “CAT INSIDE”. We decided to add them next to the door for better visibility, even when the slide-outs are in:

Hopefully nobody will ever need this information, but it’s good to have it, just in case.

Internet cupboard

I previously posted about our internet services, with a picture of the cupboard above the entry door that contains the cellular modem:

Pepwave modem:

I decided to consolidate the internet stuff into this cupboard. So I hatched a plan to run a power cord from the outlet above the windshield to that cupboard:

Cupboards

I removed panels in those cupboards:

I used my drill with a large bit:

…to cut a hole in the panel:

…for the power cord, which I pulled through by tying a strap to it:

Getting the cord through the small gap behind this speaker was rather tricky (I lost a bunch of skin):

…but I managed in the end:

Cord

I installed another grommet in this panel:

The cord then plugged in to the power outlet (the front TV also plugs in there, and for some reason the top outlet only receives power when the ignition is on… maybe I should plug my dashcam into that?):

Power connection

The other end of the cord has a power strip with electrical and USB outlets:

Then I moved the other internet devices into the cupboard:

In addition to the modem, it contains the MiFi hotspot:

A fan to cool the modem, as it gets rather hot:

And the security camera base unit, that has an Ethernet connection to the modem:

I subsequently removed the door of this cupboard, since I was leaving it open for airflow:

It’s not super tidy, but it’s nice to have everything in one place.

Cellular internet

We are both still working as we travel the country in our motorhome, so having reliable internet access is essential.

To that end, we have six internet options: two cellular plans (AT&T and Verizon) in a cellular modem, one cell plan (T-Mobile) via a Wi-Fi hotspot device, two iPhones (AT&T), and (very recently) Starlink satellite internet.

And sometimes we connect to campground Wi-Fi, when available, though our various options are usually faster and more reliable.

Having four different networks and a variety of devices ensures that almost anywhere we are, we can connect to the internet.

Some details about the plans:

  • T-Mobile (via 5G Wi-Fi hotspot): unlimited data; plan provided by the Calyx Institute. This is what we’ve used the most, being truly unlimited.
  • AT&T (LTE SIM in cellular modem): 800 GB data; plan provided by Mobile Must Have. A good backup option, though often not very fast.
  • Verizon (5G SIM in cellular modem): 150 GB data; pre-paid plan from Verizon. Often the fastest cellular option, but very limited data, so we don’t use it much.
  • AT&T (iPhones): unlimited data; plans and phones provided by Apple Upgrade Program. We use these a lot as standalone devices. They only have 40 GB data as a personal hotspot, so we don’t tether other than emergencies.
  • Starlink (satellite): unlimited data; plan and dish provided by Starlink. We’ll probably use this the most going forward, if it proves to be reliable enough (and if our campsites can see enough of the sky).

I’ll cover Starlink in a separate post later, once we’ve spent more time with it — as of this post, we’ve only had it for a few days.

This is the T-Mobile Wi-Fi hotspot; we can connect to it directly, but most of the time we go via the modem, which also connects to it:

MiFi

The modem has a roof-mounted antenna (the white fin in the following picture), which we got from Mobile Must Have, and installed by NIRVC; a Poynting 7-in-1 Roof Antenna. It contains 4 cell antennas, 2 WiFi antennas, and a GPS antenna:

Roof antenna

Zoomed out a bit:

Roof antenna

The antenna connects to the Pepwave MAX Transit modem (also from MMH), which contains the AT&T and Verizon SIMs (and can support two more). NIRVC mounted it in a cupboard above our entry door:

Pepwave modem:

See a later post about some further modifications to this cupboard.

Chair armrest adjustment

Our coach has fold-down arms on the two cockpit chairs. When we bought it, one of the arms of the passenger chair was too low. We figured that someone had put too much weight on it and broken it:

Armrest too low

However, I recently learned a trick: inside the small hole at the end of the armrest is an adjustment lever. One can put a finger in there and lift up the lever below the hole, and adjust the resting height of the armrest:

So now yay, it’s all better:

Adjusted armrest

Mind blown! 🤯

Learn something new every day.

Safe T Plus and Koni shocks

A while back I mentioned that we got some enhancements while at NIRVC. A couple of those were the addition of the Safe T Plus steering control system, and Koni shocks.

The Safe T Plus steering control system is a cylinder that mounts between the frame of the RV and the steering mechanism, to help smooth out wobbles in the steering due to wind and such, and help with control in the event of a tire blowout.

Our coach has independent front suspension using air bags, which gives a pretty smooth ride, but could be a bit bouncy on rough roads. The Koni shocks help to reduce that bounciness.

Here are some pictures looking under our coach; the yellow tube is the Safe T Plus, and the two red tubes are the Koni shocks:

3-stage water filter

Our coach has a water filter in the wet bay, to help ensure clean water:

Water filter

We recently changed the filter while sanitizing the water systems; here’s the dirty one and a clean one:

Water filters

That was actually the wrong filter, so I got the correct one:

Water filters

For drinking water, one filter doesn’t really cut it with some campground water supplies, though. So I purchased a Clearsource Ultra three-stage water filter system, with a 5 micron rust filter, a 0.5 micron bacteria filter, and a virus-guard filter:

Clearsource water filters

Our coach now has five filters between the water supply and our fridge water dispenser: those three, the aforementioned built-in filter, and the filter in the fridge.

I also bought a potable water hose to go between the tap and filters.

When first hooking up the hose and filter, I flushed them out by draining directly into the sewer:

Water filters

Then hooked them up to our coach:

Water filters

Ideally I’d like internally-mounted filters, and perhaps a water softener. One day I might arrange that, using the small bay on the other side of the coach. But for now, I’ll deal with the external filter unit; just another part of setting up at a site. Worth it for cleaner-tasting water.

Dash cover

While at the FMCA convention, one of the things we bought for our coach was a carpeted cover for our dash, from Shade Pro.

We just told the vendor our coach model and the color, and they had it ready for us the next day.

It has a grippy back, cutouts for the vents, and a separate piece for the pull-out passenger tray:
