I don't know what brand mine is, but it was a little bit cheaper and I got it at Oreilly's.
You must use trailers a lot more than a normal person. I check mine before I head out and when I get fuel and never have had a big problem. Sure I have gotten flats before, but never ruined a rim in the process.
We pull trailers a lot.
We have seven, a camper, a boat trailer, a 10 foot box trailer, a 6 foot box trailer, a 7 ton flat trailer, a 7 ton dump trailer, and a 7 ton gooseneck, thus this thread
