Hi Rick,
We LOVE our 13 foot Scamp. Ours has the front bunks, currently sleeping our 12 and 14 year olds comfortably (100 lbs and 65lbs). The dinette makes in to what is probably a wide twin size, not quite full sized. That being said, we sleep comfortably together on it. My husband is six foot, 220 pounds and I'm about 5'6", 115 pounds. It doesn't feel too tight for us. I THINK the length of the bed is 74 inches. I usually sleep against the wall because the curve of the back makes that area a bit shorter. We don't have A/C in our Scamp, and after one season camping, probably won't add it in. I bought some battery operated/electric combo fans and those have worked great. We only used them once in Nebraska when the overnight lows were only 80. We have a screen door on our Scamp that we leave open through the night and with the vent and windows open, mountain camping has been lovely. If you have any other questions, let me know!

I have a question about the 13 Scamp. Does it have the front bunks and the rear main bed. How long is the bed? Is the main bed like a double bed? Is the A/c thru the wall and not on top?
