I'll add my endorsement to the Equalizer anti-sway hitch...which has won the Trailer Life gold award 5 years in a row, selected by readers as best on the market.
I purchased mine with my XT276 FunFinderin 2012...dealer set it up and have never experienced one iota of sway even pulling the 30 toy hauler with a 04 Ram 1500. I have since upgraded to a Ram 2500 and simply readjusted the hitch for the increased height of the 2500 from the 1500........easy to do.
The Equal-i-Zer hitch was the best purchase made with the camper!
