I just purchased a new Rockwood 2910 TS with the upgraded 15,000 BTU AC unit (standard was 13,500). On my first trip out it wasn't cooling well and the dealer checked it and replaced the unit.On my second trip, I went to the coast and the daytime temps were a high of 87 (high humidity). The first day it never got that cold (probably the fact we arrived at 11:00 AM was a factor).That night it got pretty cool in the trailer. But the next morning by noon, it was getting warm inside. Put a thermometer on the ducts when opened below AC and the air was coming out about 65. When those were closed so its pushing through the ducts, those temps are just several degrees warmer.But the temps in the trailer went up to about 80-82. The outside temps, was in the high 80's or close to 90.I would expect the 29 foot trailer to cool down better that that with the upgraded AC. Can't imagine what will happen in 100 degree summer heat. Has anyone else seen this with the Rockwoods? Should it have 2 units for a 29 foot trailer?It's wired for 30 amp, so a 2nd besides adding some weight to the front would require some rewiring.Am I expecting too much?

With my experiences with a 2011 Thor Fourwinds 25c (sold), It had a 13.5k on it and in 100* heat with the AC blowing it was hard to get it below 80, But I was out in the open on a sunny day, shade plays a big factor. Now with my 5th wheel with just 2 units running (15k&13.5k) in my 40 footer which is also out in the open it can hold the at 78* and still cycle on and off. And if thats not enough I can always start up the 3rd 13.5k that I installed on my bunk house. But a 15k on a 29 footer, sounds like it should get under 80. Does it have a dark colored roof or walls.

Measure the temp of the air going in and coming out of the AC. A 16~21 degree drop is the best they can do. If it's doing that then you need more AC.

I had a single 15k BTU unit on my Weekend warrior, which was 41' total (37' box) with a small slideout. It had no problem keeping the trailer cool even in hot humid summer in Charlotte, NC. The trailer seemed to be well insulated however, with the exception of the slideout and ramp door. I would have to pull the slide in during extreme lows in the winter, but never had to in the summer. Does your unit have the tan exterior? If yes, that is no doubt a factor. Even though isn't very dark, it will still absorb a lot more heat than white. I also noticed that many new trailers have tan roof membrane now.I almost bought a new Outback with the Mocha exterior, tan roof, and black front cap. I'm glad I didn't, even though the color scheme looks really sharp. So far I've been on two trips with my new Creekside, which is all white, and even when its 90F outside it stays cool enough inside I have not needed to run the A/C yet.

Well that Texas heat and humidity can do that to most RVs, I know when we camped San Antonio and South Padre the AC had to run 24/7, arrival day it would finally catch up in the late evening, and as long as we never turned it off it kept our 32' rig comfortable over the rest of the stay. FR states your rig's length at nearly 34', plus all the slide-outs adds to the difficulty your AC encounters trying to cool down a large TT. I use a temp gun to monitor difference of incoming and outgoing air from our AC unit, usually see a 25 degree difference but it still takes some time for it to cool the entire interior of our rig.

We're in TN where summers are hot and humid. We only camp where we can find shady places which are in the COEs and SPs. The A/C in our 28' NT-BRS is adequate for the hottest days. I don't know if we could or should expect to be as comfy in our RVs as we are at home. My TT is white with a white roof.
