I think 850 is really high for mounts only. I installed mine in a couple of hours. I'd check with hitch installers if you aren't doing it. Model numbers for different years are on the Torklift website. They make mounts for non-eom hitches including their own.
I like my fast guns, but I don't know what is a good price.
