carrying a boat along with trailer......any of you do this?

I made a metal rack that slides into the bed of my Pick up, I carry a 18 foot canoe, or for solo my 12 foot canoe, I also carry a 12 ft jon boat , mostly the 18 ft canoe is my boat of choice when taking a fishing partner. I also have a 10 ft plastic pontoon boat that I slide into the bed and lean it forward then tie in down in the bed of the truck.
