I have a 34' Tail-gator 5th wheel with seperate garage. In temps well above 100 I can drop it about 30+ degrees in about 1.5 hrs. This trailer seems to be insulated better than the WW I used to have. It's ducted and I shut off the vent in the garage. The interior cover on the a/c has been replaced with one that has vents on either side that close to push it all through the ducts or open the to get more air into the living room. The open style toyhaulers without ducts are hard to cool. My WW was that way and it never worked as well as this setup.
To run 2 a/c's min would be a 5500.
