I've been towing my 30' TT just fine and love it. I bought my Equal-i-zer setup and Prodigy kit from
RV Wholesalers. I've adjusted my WD setup to be very agressive. I have all the washers on the support bolt and moved my Bar Brackets up to the second from bottom hole. I push the Tow Mode button, shift into 4th and away I go. I have shifted down to hold 3rd or 2nd for climbing or descending a couple of steep hills but no big deal.
Yea, it's not a diesel but I don't need a 3/4-ton for my DD and this puppy pulls really nice IMHO. From what I've seen, the 3/4-ton gassers don't seem to be much better but I could be wrong. I'd have to agree with Buddha and say take that hitch back for a full refund and get one that actually works. I don't see any reason why a Titan shouldn't be able to pull that TT with just the proper hitch and brake controller setup.
