Concrete / Grandy Creek KOA Holiday Thousand Trails

We stayed at Concrete / Grandy Creek KOA Holiday in Concrete, Washington. (Campground Reviews listing.)

An interesting hybrid park; about half of it has Thousand Trails sites, about half KOA sites. We stayed in a Thousand Trails site, so free for us. No sewer, and only 30 amp, but that’s fine for less than a week.

Here’s our review on Campground Reviews:

Close to North Cascades National Park

We stayed at this park with our Thousand Trails membership. It’s also a KOA, and each site is marked with a green or yellow utility box depending on which “side” you’re on. There are very few 50A full hookup sites allocated for Thousand Trails, and most of them seem to be taken by seasonals, so we were stuck with a 30A site that didn’t have a sewer connection. Most of the sites seem to be electric/water-only. It was in the 90s while we were there, but luckily, we’d recently had SoftStartRV units installed on two of our ACs, so we were able to have them running even with the 30A connection. Between the narrow roads and the large trees jutting out into the roads, it was a little difficult driving and parking our 40′ motorhome. Once we got settled, the trees were nice cover from the heat of the day. They seem to be having severe staffing issues as the camp store was closed the whole time we were there.

On top of not having a sewer connection, the one and only dump station was out of commission for our entire stay. They finally opened up a sewer site (back in) for folks to dump, but what a hassle that would be. We waited until we left and made use of the excellent facilities provided at the next rest area on I-5. We camped at Concrete / Grandy Creek KOA Holiday in a Motorhome.

The site was sloped up at the back, so the front was fairly high with the coach leveled. So I used the accessory step:

The utilities — 30 amp power, 45 PSI water, and no sewer (at Thousand Trails campgrounds it’s fairly common to clip the check-out date to the power pedestal):

To help the jacks get level, I added some plastic leveling blocks. The first time I’ve tried them with our coach. They are supposed to be rated to 40,000 pounds, but I’m not convinced:
