I've hauled several lots long distances, up to about a 10hr drive so far for the longest, and let me just say this.
U-Haul sucks.
However, I recently had to move 15 machines about 40 miles, and used the biggest Budget truck (15' I think), so much much much better. Their biggest truck fit 15 machines (had to lay one down in the rear due to the rear door lowering the ceiling height when open) comfortably, and was about 100% nicer than the U-Hauls I've used. Cheaper as well, just be sure to say you're a commercial and make up some DBA name (doing business as...) and you'll get the cheaper commercial rates.
If you have some old cardboard boxes, you can use them in place of shipping blankets, but I'd try and blanket any of the really good games from rubbing into others. Use a cross strap every few rows (though I'll admit when lazy I only do two straps across the last row).
My final suggestions is to avoid 10hr long trips with U-Haul equipment.

That was one long day.
