I use to use this " contraption " , which served me well fer six years .
The con of it was the support was carrying the end load , and the frame that supported it was the full length of the bed , although it easily slid out the back end .
This past summer , i retired the old frame to the firepit fer a weenie roast in the backyard .
Built this simple " Y " out of maples and pine harvested outback .
The difference , the " Y " doesn't carry a load and thus the canoe can rest on the cab without it .
It's simple purpose is to allow for a snug tie down to the back , without putting strain on the gunwales . Also allows me to get a real snug tie down with no worries of canoe movement with passing transports on the highway .
I took the next picture this morning , just to show you how portable it is and no concerns from the insurance company as i asked my agent .
