A hitch of any kind to carry bikes is unnecessary ... a few scraps of plywood and you can easily carry up to 4 bikes in a 1/2 ton truck bed, even a short bed.
The last few years I haven't bothered taking bikes as our boys no longer camp with us so I cut this DIY bike rack down in size, hung it off my garage wall, and still use it to this day to store my fresh water Aquatainers. However, I
could and
may still use this season to carry bikes for my wife and I, along with the usual stuff I carry in the back of the truck. Works like a charm and cost nothing to build. :B
