Yeah, I hate to sound like a snob but, if you're goin' on a big run with a bunch of rigs and they state lockers are required for the trail then leave you're open diffed rig at camp. You're gonna' piss some people off. My rig is pretty ghetto compared to others but I got 2 lockers and spare parts. Would you be somewhat annoyed on the 'con if you came accross some guy that was stuck and out of oil. I mean if the guy was all like " Hey dude, do you have a tow strap? Ahh jeez, dude. Do you have any extra oil?"
Go prepared. Wheelin' your stocker is cool. We all started with that but, don't go on a "lockers recommended" trail run with a line of 20 rigs behind you. All your' gonna do is piss a bunch of people off behind you while you're gettin' hung up on a bunch of gay stuff.
Besides, they have "powder puff" runs that are fine for a stocker. Hell, hook up with a H2 club.
