It is a special form of entertainment to see someone failing at loading/unloading an offroad vehicle.
That said...when I was about 20 years old working at a Kawasaki
/Yamaha dealer, a customer bought a little Kawasaki Bayou 220 quad and I was assigned to load it up into his truck, an F150. I had never ridden a quad up ramps before into a truck, and sitting in front of it, this ramp looked to me like it was about an 80 degree incline. On top of that, the torque and power of the Bayou 220 required throttle control that was just beyond my capabilities at the time to make a safe and controlled climb of that sort. Not one to back away from such a task, I got an appropriate start up the ramp, weight forward, but quickly realized it wasn't going to make it, so I pinned it, with my hand and foot nowhere near a brake control. I came off the top with the front end still at about the same angle of the ramp and and wheelied right into his truck tool box. Thank goodness it was there, because otherwise I would have been buying him new back glass. No real damage was done, just a few small dents and scratches to the box, and he was surprisingly forgiving. But I sure felt kind of dumb - especially when I walk back towards the shop to find an audience of co-workers watching, laughing, judging.
