Be careful and do some research. Tire size and straps may not be the only problem. I don't know what you're towing with, but a lot of U-hauls you're hauling anything other than a smart car with their trailers, won't let you haul things, and say if you have anything less than a 1 ton it can't be hauledThink it's a liability thing.
Also keep in mind, I'm ASSUMING by the pic, it doesn't have a trailer brake, I know that's a generic picture, but I've personally never seen a nice quality trailer at u-haul or any of those places with nice tandem axle trailers with electronic braking. Blazers are heavy man, be careful, you said you're going far.
We are using a 20' U-haul truck to haul this trailer. Someone else is driving the truck. My mom set this whole thing up.. if I had my way we wouldn't be going but I'm not in a position where I have say unfortunately. It's a long long story though...
supposedly the guy knows what he is doing but I sure don't have faith..
Here's another shot of it..
