oop thanks for telling me dude..
what to bring to blazerfest eh?
ALL your camping gear. All your spare parts for your truck. Extra fluids for when you flop over, or break a front driveshaft and crack your tranny pan, and leak all your fluid out. anything you think might be iffy or anything you might break or need on your truck you should probably try to get it figured out and get a spare before you break your truck with us.
What might hollister claim on your truck? MAke sure your drivetrain is pretty water tight if you wanna try any mud. ive seen numerous motors and trannys smoked at hollister. front driveshafts, axles, and ujoints are common breakage.. i've seen rag joints and brake lines, etc. busted as well. fire extinguisher is mandatory (the curse of hollister hills) a few blazers including mine have caught on fire there.

tires popping off the bead is always a part of every trip.... you could be THAT guy this trip. pack a spare.
ah, lets see what do i always forget, sleeping bag, mattress, silverware, plates, mustard or bbq sauce, food, water, alcohol...
