Kirkham's is OHV friendly, just not jackass friendly. They are all about backcountry off-pavement travel (owner Jack drives a modded FZJ80 and had a 60 before) but against those who thrash the land, leaving their shit all over (literally).
I know both of the brothers who own those 4runners, lifted, locked, etc. I worked there in the past. I prefer Kirkham's over REI or the like simply because the people know what they are selling.
