Please check out the UHaul
Campers page on Facebook. There are many nice owners and enthusiasts who should be able to help you out.
Have you checked out the albums section here? There are many iterations of what you're looking for. I purchased 4" thick memory foam and cut it to fit. I use my "dinette area" as a full time bed. A great idea is to take the front bench as members Pam Garlow and Tom Griebe have and make it a full time dinette area. This allows you to keep the dinette area as a full time bed, which is pretty darn convenient.
I also keep my bed made full time as I do most cooking and eating outside. I use my CT mostly as my sanctuary/sleeping quarters.
