We have a amerilite 25bh and are very happy with it.
We see temps from 25 to 100 and stay comfy. It also has held up on the rough roads where we boondock.
I weigh 220+ and the benches don't sink on me.
My one complaint is the mattress. You'll need a topper or like we did just replace it.

We have a 24BH and love it. I am 250# and have no problem with sagging benches or beds. I agree with Jim's mattress assessment though, it is about as thick as a slice of bread. The topper was the best investment.
Since I last posted in this thread, I purchased a 2011 Ameri-Lite 255BH. I LOVE it. I don't have much experience with it yet, but I can say that in the 104 degree heat, the A/C almost froze us out of there. So that's a good step in the right direction!
The original owner upgraded to the mattress topper and it's wonderful.
