No matter what you buy, there are tradeoffs. Weight, towing, storage, accessories, capabilities, tank sizes, cost, etc. What helps is to make a list of what you must have, what you want, what you won't put up with, etc. Then score each item to help decide what best meets your needs.
I will say a TT of the same size usually costs less than a 5er.
