I read someplace that the quality of the Little Guy T@Bs is quite a bit better than the quality of the T@Bs built by the previous ownership. But if you found a preowned one built by Little Guy and the price was low enough, it could be a good buy. That way someone else took much of the depreciation hit.
On the other hand, if you can't find a bargain like that or if you prefer a new unit, Scamp
is the better buy. Don't worry about service after the sale, because the FG shell is pretty much problem-free and the rest is basically standard RV components that any RV place can work on.
