So I will be moving next year to Oregon and needless to say my only vehicle is a blazer. I want to put a hitch and everything on my blazer so I can tow a uhaul trailer. What would you guys recommend? I was thinking of a 5×8 cargo trailer.

 

A typical class III hitch is all you should need. Brand doesn't really matter in my opinion, they all do the same thing.

I bolted on a used Draw-tite brand that I picked from the local junk yard onto my 04 Blazer and have moved 3 times and yanked half a dozen stuck vehicles out with it now lol

 

I got mine at Uhaul a number of years back. If you choose to buy new, be aware that a number of places will tell you that you can't put a Class III receiver on a Blazer for some reason. You may need to show them in your owner's manual the tow capacity of your ZR2.
