The only difference between MH's and TT's is the front seats and the engine in front!
Neither of which you can utilize as living area!!
From there on back the innards of the RV's are all the same.
You will lack some of the storage but I've seen new TT's with the same amount of bays as some MH's. But then again you do have the added storage space of the back of the pick up truck.
I full time and I have seen ALL types of RV's being used as a full timers RV. It's what ever floats YOUR boat.
Met one lady who's DH passed away and she traded in their Big ole Class A on a real nice Casita and continued full timing.
I choose, after owning a TT...a MH. Only from the standpoint of being able to just pull in, park, and open a cold one. No fuss, no muss.:W
