Weldor, the metal fusing hobbit?
Best thing I've found is to make your fleet uniform, all pintle/ring that way you can bolt a heavy pintle directly to the truck. Pickups can have custom bumpers built with an appropriate pintle installed. Receivers are always the weak point. A company I know of who works at a lot of estates has one installed in the front bumper, instead of trying to back a chipper down a long driveway, un hook it spin the truck around and push the chipper in.
