If you or a buddy are handy with a welder ... make one. I used 3" square tube with 1/4" wall 4" angle for the side brackets. Bolted to the frame with six 1/2" bolts. It's towed my 2000# squirt boat for years. Receiver hitches are ok, but this solid setup takes the rattle out of the combination. This same hitch has been on my 2005 and 2011 Montanas as the frames are spaced the same. I had a similar, but a bit lighter hitch on my 2000. It didn't have the true I Beam frame the later models have. The reason Keystone doesn't endorse towing anything behind your fiver is there would always be that brainless someone that tried pulling a 34' Scarab with twin 502's.
