Welcome to the forum.
We are on our 7th unit--from small TT to now 38' fiver. Wasn't near the selection when we started in '79, so research is necessary as you are doing. Suggest you don't buy new if planning an upgrade in 2-3 years. Any brand you consider, take a close look at the owners' forum for it...can be very enlightening.
Good luck, good hunting.
