I have been bouncing this idea around for a while and I finally didi it.
With four of us traveling around on a regular basis, sometime six if the kids bring a friend each , we find it hard to bring all our bikes only two will fit in the back of the truck without making a tangled mess.
So I thought why not mount fork clamps to the dinette seat plywood and carry the bikes in the TT?
First I needed to beef up the plywood from 1/4" to 3/4". This I already did to make the dinette cushions level when configured as a bed.
Next four - fork clamps @ $25 ea.
and eight - 1/4" bolts with washers and nuts @ $11
Total bike rack cost $111 +tax
Mounted 4 - two on opposite bench seats:
Flip plywood and replace cushion to use couch:
