now, i have 2 ropes with hooks on one end of each hanging fromt the garage cieling. i back in,slide the ropes in under the top, latch them to rope loops on the cieling, and drive out. no problem. before that, i slid old towels between the bed and top, then slid it back until i could balance it on my back. to put it on, i propped it against the towels, shoved it straight up, then walked it back on. you don't have to be huge i'm not (5'10, 190) but you do need to be strong enough to control the bulk. my friend is about 6'2 200 and it squished him when he tried it. glad i was there to catch it, not that i recommend that. "buddy system" is the way to go when you can, i say.
