With dual opposing slides in the living area alone, it will feel a little like home when you first step in. Foil tape works really well for both of these purposes, and it stops you from LOSING the air to blow needlessly into the space between the ceiling and the roof.Three slide outs are responsible for giving this Cougar X-Lite rear living fifth wheel by Keystone RV its spacious feel. Additionally, it helps to seal the area between the seiling and the duct. Just be VERY careful that you don't try to put a vent PAST the end of the run!Īnother GREAT modification is to make sure that the plenum (the area inside the unit that directs air into the ducts) is sealed appropriately. The one on the curb side of the camper runs to the front, and the one on the street side of the camper runs to the rear. there are two runs of duct from our unit. However, we found that with these modifications, we can manipulate the temperatures to satisfy ALMOST all the time. Honestly, the 13.5K BTU air conditioner really isn't enough, particularly if you have a big slide-out.
#COUGAR X LITE 31SQB PLUS#
On all four of the orginial vents, plus the three I added, I used dampable vents that can be closed off in the areas not in use. I added two vents in the living room area of our 29RLS, as well as one vent in the bedroom. They'll also caution against it if you push them on it! (You don't want to constrict the flow too much, or else you will cause the unit to ice up) Keystone won't "recommend" this, because to do so would be to admit that they didn't do a great job engineering it. If you expect to keep the temps in the very low 70s when the temps are well into the 90s and there is no shade, then your expectations are not realistic in my experience.Īctually, a better option than adding another AC is to add vents. This is normal for larger TT (30' +) in hot areas with one AC. Next step would be a slide topper for the superslide (have not needed yet) It would be nice the add an extra AC except you would have to convert to 50 amp service at high cost. This will mean less cubic feet to be cooled and the top of the slide has less insulation. We also can bring the back bedroom slide in during the hot part of the day when not in use.
#COUGAR X LITE 31SQB WINDOWS#
We made velcro attached insulated covering for the windows on the side of the camper facing the sun. We have learned to do a few things to help the AC out when temps are high and there is no shade available. I checked the drop in temp from intake to output vent and the AC is dropping the temp 21 degrees, so the AC is working properly. When I camp here on Louisiana and the heat index is 95 to 105, our AC runs continuously from about 10 am to dark to keep the interior in the 77-78 range. LA Adams post above was dead on in my opinion. Sold Trailer - not RV'ing at this point in time Here in the midwest and at our CG's with shade, the 13.5 does a very satisfactory job - out west in the desert - not so much!!!Ģ000 Ford F-250SD, XLT, 4X4 Off Road, SuperCabīanks Power Pack w/Trans Command & OttoMind Most TT's have marginal insulation at best and a 13.5 or even 15K BTU AC unit is marginal with the current insulation and building techniques if your camping our west or in the south in the direct sunlight. After the sun went down, it started to cool off inside and by 11PM we were down in the low 70's and were able to sleep.

With the AC running full blast, the coolest I could keep the TT during the day was about 90 degrees.

When we were out in the 4 corners area 2 years ago and at a Monument Valley CG it was well over 100 degrees outside and there was no shade at the CG (basically a desert). It does take a while to cool down and it helps if you have a bit of shade. My 31 foot Nomad also has only a 13.5 BTU AC.
