No one can guess how you’ll adapt to a smaller space but you. But based on your initial comments you’ll likely feel confined and whether the tradeoff is worth it is the big question. I think there are other aspects beyond just the space, though. Pulling a small TT does have some pluses. Better gas mileage, much more flexibility in roads you take, places you can go, access to gas stations and such, and opportunities for camp sites. Plus you can park the TT and use the TV to explore or make a run to the store. And you can easily access public lands where the camp fees are peanuts compared to commercial parks.
On the other hand, The TT will not have all the amenities of your MH so that’s a tradeoff to an extent. And if you’ve always traveled in a MH and commonly get sites with HU’s and want HU’s for the TT you’ll sacrifice some of the advantages of the small TT to get in about anywhere, the more pristine spots as a rule don’t have any facilities.
I have to admit to being bias; I’ve been pulling a 16’TT for 25 years and have no desire to go to a MH. I wouldn’t be nervous about pulling a small TT, if set up properly and kept away from you TV max ratings I think with a little practice you’ll find it a piece of cake. Mine is. Good luck on your decision.
