We came from a canoe and tent background, then we owned a PUP which added to the convenience of camping. However, the biggest change when moving to a TT was the loss of the feeling of camping.
It is true that you can always cook, eat and play outside, indeed some TTs have an outdoor kitchen. Still the reason for a TT is to have "all the comforts of home" and in my opinion these comforts steal some of the feel of camping.
In theory the TT can serve only as a waterproof tent but in reality you have a portion of your home, that needs to be heated and cooled, which you are dragging everywhere you go.
We bought our TT because we wanted to travel without the hassle of set up and take down and move easily from point to point. It serves this purpose very well. But things like cold mornings, packing wet, sharp winds, ice chests and critters hoping to share your tent are lost. These are all part of the feel of camping.
I always suggest renting a TT the size you want and try before you buy.
Good Luck.
