There are so many TT's out there it is hard to suggest one. I do believe you should look for an island bed so each person can get into bed without climbing over another. We are in our late 60's and had to replace the thin mattress that came in ours, due to back aches. We ordered an 11 inch Nuform with memory foam on top from Overstock dot com. That did the trick. If you like the 50's and 60's retro look, Take a look at the Whitewater Retro by Riverside mfg. The have 18 ft and a 24 ft model that are very nice. Ours is a 24 ft model 195. Best wishes on your hunt and may you have good safe fun.
