First trip...rear AC issue

[Silver_]

We were able to get out with the new 364BHL to Palo Duro for the long weekend since we already had reservations. It's just up the road, and we've been coming here for going on 40 years. We got here around lunch today and set everything up.

We started the rear (main) AC but it wasn't doing much good. I figured the heat of the day (around 90f) would take some time to push away. I checked my amperage draw and was able to switch on the front AC as well by running the water heater and fridge on propane. The front AC was working much better, and after several hours, the front AC was pushing cold air while the rear AC was room temperature. It wasn't frozen, the fans were running fine, and it was drawing appropriate amperage as if the compressor was running. I could hear it kick on when we switched it to AC, but no cold air. The coils were super hot up top.

I ended up just running the front AC and keeping the rear unit on fan only. Luckily it's cooling off outside, but it's a bummer that our larger AC isn't cooling and can only act to add some air pressure into the racetrack ducting.

The camper will be out here until Thursday, and I'll have to get it in the shop to get checked out when we get it back to Lubbock.

Do you guys think it's a refrigerant leak? It was working great at PDI but has sat in covered storage for several months since then and has had time to leak down if that's what it is. Unfortunately we don't have a way to plug in and check function before heading out as we only have 110 at the storage.

Anything to check while we are here? Thanks.
