When I go out, and am not near my truck, it is a day pack, wheel wrench, SAE and metric Allen wrench sets from Home Depot, screw drivers, needle nose pliers and needle nose vise grips, a plastic tray to put the stuff I removed into, misc. extra hardware and fasteners, zip ties, electrical tape. Shock oil. Extra batteries for the tx and rigs. Bottle of water to hopefully put out a fire if my rig went up in smoke. Sometimes even extra wheels and tires. I guess I’ve been to too many Baja off-road races.... redundancy. Oh yeah, add the tripods and cameras strapped to my back pack.... Carrying the Bomber and Capra while hiking to my favorite spot. Workout, yes, able to perform quad bypass on the trail, yes for the most part. Always 2 rigs, so if one fails. Heck, I’ve even packed the small Rigid cordless impact gun and tips a couple times. It would suck to get out, only to have a mechanical issue DNF your day prematurely, especially if it were a commute to get there.
