I have a super hitch and extension. SOld the extension when I went to a TT. Now I'm back with a TC and a boat. I didn't want to buy another expensive extension and went with a cheap 24" in single tube extension from a truck store or something. THen I put a 16" drawbar in it to make it reach out from under my TC fully. Seemed like a great idea. Went on a road trip and my 200lb toung weight boat bent the extension down about 2 inches. I flipped it over for the trip home and it bent it straight, then about 1 inch down going the other way. Just do it right with a proper hitch and extension.
Craig's List is your friend!
Found a 33/34" superhitch extension with wiring, chain mount, and 7 pin round mount attached to the hitch...$150. Sure beats $600. You can probably find a super hitch used for 300-500.
