Buying used is a great plan. Be aware that TT tires are usually good for about FIVE YEARS. Granted, in my case, it's an opinion gleaned from all the posts here. ST (special trailer) tires have a date of manufacture code on them. Look up how to find that and check on any used trailer you are considering, could be an immediate expense.
I bought my my 1st TT new last year but I searched and found a great deal on it and it was 150 miles away to get the TT I wanted for a price I would pay. IIRC, it was either RVfinder.com or RVlocator.com that I located it with. I found Utube video tours to be a great help on comparing features.
IF you can sleep comfortably in a bunk, there are several smaller bunkhouse trailers that use a Murphy bed (fold down) for the master bed that when shut up has a large couch in front of the bed. Then you get a couch and sleeping options in a smaller unit.
