I bought a TT and now more questions

You might 'get by' without a WD/sway control hitch, but why just get by? No use taking chances with a tail that long, because you never want the tail to wag the dog. I'm partial to the Equal-i-zer for a trailer like that, but there are others as well.

Oh, and how to keep your wife from overloading the trailer? Make her sleep in the truck... :D
