Looking to add a second Air Conditioner. The TT I am buying has one 15k btu and I live in Florida. It was suggested that I add another roof top. Any suggestions to which one I should buy? Thanks for your advice in advance...

Look at Coleman/Airxcel, not sure who is the mfg, just know based on reading the new Dometic units seem to have quality issues. Here is our unit. Our rig is a wide body 38".Airxcel 48204C866 08-0080 Mach 15 15.0 Arctic Wht UpperWorth doing some added research. Opted for the extra BTU's. Ours cost just under $700 on Amazon including delivery.

I have one (And an Advent Air with a coleman fan on it).My Favorite RV Girl (She is a mobile RV technician) Says that "Colemans SUCK" (in a good way) And others blow By SUck/Blow she is talking about the direction of air flow through the condenser.. Colemans SUCK air in and blow it out the sides What does that mean.. Well from time to time I get Cotton-wooded.. And this clogs the condenser.. So with the Coleman I remove 4 count 'em 4 Screws from the TOP. Life the "lid" and peal the condenser clean then brush off the last bits and replace top and 4 Screws.With others it is like 10 screws along the bottom of the outer cover (Cowling) and then you need to remove an INNER cover. this can range from a few screws to cutting tape and bending tabs. Then if your hands are my size remove the fan from the shaft. then I can clean the INSIDE of the condenser.Way more work.. Way way more work.

Make sure you can actually add it first. We wanted to add a second one to our previous travel trailer and was more than willing for our dealer service shop to do the work. When consulting with them, they said they wouldn't do it.First, the vent over the bedroom was not wired. I suggested just putting in the air conditioner and run a separate wire so I could plug it into a normal 15-20 amp outlet. I'd run an extension directly to the campground electric hook up. They wouldn't do it.Second, I asked them about adding the wiring inside the camper, and they reminded me the camper was a 30 amp system and the entire camper would have to be rewired for 50 amp. We're talking big money there. I didn't want to do that.We ended up switching the 13,500 btu for a 15,000 and stayed with just one air conditioner and it actually worked pretty good for a 35 foot TT. But... we camp in Florida in the month of December too! In the Northern states, it's very seldom THAT hot. It turned out the single 15,000 BTU was the best solution for us in the long-run.So, just an FYI... make sure, before you go out and get all the hardware and spend a bundle on a second air conditioner, it's actually do-able on your camper.Of course, if you do the work yourself, everything is possible! Dealerships and service centers have to follow rules and legal guidelines and also have legal obligations and can face law suits if something went wrong down the road. So, in order to avoid things like that, I think it's just easier for them to say, "No, it can't be done."Edit:I still have that 13,500 btu air conditioner sitting in my utility shed at home. I'm still trying to give it away to anyone who wants it ... been making this offer for 5 years now. Hope the mice haven't chewed up all the wires now.

Absolutely love our new AtWood AirCommand (no heat) AC. It is amazing how queit yet forceful the air comes out. Can feel a cold breeze 20' away and carry on a conversation with it on High.

Thanks...Was thinking about going with this Atwood 15027 Ducted/ac unit. I am reading great reviews for a 15k btu that is equivalate to a 18k btu unit.
