Winged One, that home built setup looks pretty snazzy- but I think I'm not enthusiastic about extra length off of the back. Plus, I'm already really pin light (only about 17% loaded).
The Buggy World is closer to what I imagined, though I have to say- the idea of driving up a ramp like that makes me pee a little.
๐ Not sure how much effort it would take to assemble/disassemble the side rails each time. I have a crew cab truck, so I should be able to keep the cart almost fully up there without a whole lot of overhang.
Laknox, good stuff- I hadn't thought about hitches like the Automated Safety Hitch (or equivalents). Seems like it could be a solution- though again, I worry about the length of my setup. That looks like it would add 5'-6' (best guess).
