stay clear of the Load binders...
I use the ratchet straps made for car.. I think mine were from northern tool, but I know various others make all kind of styles, cost. What I use is 4 ratchet straps with 4 axle straps. The uhaul trailer has built in tire straps for the two front tires, but with 33 or larger tires you will not be able to use them. The uhaul trailer also has built in d rings on teh inside edge of the trailer for using your own straps, plus it has two bulit in safety chains. I "x" the straps front and back, One ratchet and one axle strap per each side, then front and rear. I'll post up a pic a little later of the straps.
33 * 12.50.. tires is what I run
One things is this.... history makes no difference with the uhaul place, I've found that every store is different. Some are "anal" about the rules, others could care less. Personally you need to have the right rated hittch and reciver along with the right tailer ball. Max is 2 inch ball on these trailers, they also have surge brakes in place of the 7 pin electric type.

axle straps loop around the axle, ratchet strap connect to the d-ring on the trailer and then connect to the axle strap.
Generally its a good idea to run strap from drivers side d ring, to passenger side axle strap.
Then from passenger side d ring, to drivers side axle strap. This is the "x" pattern. Then of course you loop saftey chains around approprate parts.
Best to tie down from front and rear axles, 2nd best would be from frame, third might be from d rings on truck if you have them front and rear on bumpers. I would avoid compressing the suspension on the towed truck unless you have no other choice. They also make some things called "cluster hooks" that have tie down connectors made into them like they use on the car haulers that bring new cars into the dealer ships. Many frames have slots, or other type holes made in them from the factory to facilitate these type of connectors. You'll be fine using appropriatley rated straps like I linked to, making sure they don't get cut or damaged with too much grease or crap on them for extended periods.
If you need a pic of the straps... let me know.. I think the links should give you a good idea. As stated..there are multiple versions of straps and all kind of stuff. Everyone will have their own idea of how things work for them. I do what's safe and proven. I drove a wrecker for a few years and have towed all kind of garbage both on conventional wreckers and on roll backs.
Dont waste your time telling the uhaul people the details about your truck you are going to tow... it will only cause you aggrivation.
