Welcome Jim,
With a 5000 Lb. rating, you can tow almost anything
fiberglass, except for maybe some of the real big Bigfoots. You did not say what your TV was though. Your basic limit will be the height. Double check how high your garage door actually opens and go from there. There are tricks to lower your trailer to garage it.
There are some nice trailers in the
for sale section here. Check out

Drop into a
rally, there is a big one on the N shore of Lake Erie next weekend or you can find others on the
rally map. That way you can compare first hand what brands you like and what features suit your style best.
Many of us have traveled 8 or more hours one way to pick up a trailer.
