I've heard that at best you should get an inside trailer temp of about 20 degrees less than outside. I live in Texas. It's 94 outside right now and about 78 in my 5er. I have a 32 foot Montana with one 15,000 BTU A/C. BUT, I have the arctic package (upgraded insulation). It is a 2004 so the insulation package isn't as good as the newer models.What do you guys think about what my results are (good/bad) and what are the top 2 or 3 things I can do to reduce indoor temps.I've been hearing about using the aluminum bubble insulation stuff on windows I don't need to see out of. Any other suggestions?EDIT: I'm also looking into tinting the windows. Anybody done this?...what brand, type, etc did you use?

Probably about as good as you can get. I would suggest a second AC unit.

You misheard. An AC drops (at best) about 20 degrees across its coils. When you turn it on in a 90 degree rv, the AC starts spewing out 70 degree air But as the air starts to drop, now the air inside is a mix of 70 and 90 degree air; say 80, so the AC will now be putting out 60-65 degree air. I have two acs in my 40' DP and can easily get it in the low 70s in full sun on a 100'degree day.

Only 1 A/C (even 15K) you are going pretty dang good.Got any roof vents........stuff a accent pillow in them to block the sunlightOur rear window had a large day/night shade that took 2 to raise/lower plus recliners were in the way.Replaced it with 4 black out curtain panels.......closed they dropped temp in recliner area significantly. Extend awning as much as possible....helps shade side of rv Clean return air filter routinelyKeep the EVAP Coil CLEAN

A/c output 70 degrees. Later on, 80 degree RV, a/c output 60 degrees. later on 70 degree rv, a/c output 50 degrees. later on 60 degree rv....etc etc. But in reality, that doesn't happen.Why?
