SOLD!
I have a pair of these from before I got a low enclosed trailer with a huge door. They worked super well, are very light, fit together nicely, and are in fine shape still. Here's a pic of them with my old trailer. 818R in race height loaded on these so it will probably work for most trailer/car combos.

I'm in Western NC but I travel a decent amount and would love to deliver/have these picked up and not have to ship them. Asking $450 on craigslist, $400 for the FFR forum
