Sounds like a toyhauler might be a better choice.
The great thing about the garage area in the toy haulers is once you empty out all of your toys, the garage can be converted into living space.
For fulltiming you want to get an RV that is comfortable and large enough to carry all that you want to carry. I always use this test:
If I get caught in bad weather and stuck inside the RV for 2 weeks solid how small (cabin fever) would a 26ft TT feel vs. a 32ft 5th wheel/toyhauler ???
We went through a week of heavy rain and snow and were glad we had 38 feet to survive in. The walls never began to close in on us. I can remember in our 24ft TT we would go in to town and walk through the shopping area or take in a movie when the walls began to close in.
