Had a TT years ago. When we went back into it we bought a class B. Liked the gas mileage and it was great for me and the dog but just too small for the wife and I on any longer trips. Decided we didn't want anything that did not have a full time bed as a bed you have make up and take down is not just a pain but it limits what you can do if you have different sleeping schedules. I like to stay up later and get up earlier.
Wound up with a class C that is 27' with a queen bedroom and can still fit in most of the campsites we like. Anything bigger would not work for us.
