not real worried about my first trip just a weekend 40 mile up the road, but trip #2 is 1000 round trip, besides the spare, jack, screw driver and rat set, basics "WHAT DO I REALLY NEED TO TAKE TO FIX...
I don't carry an entire socket set - I went around the rig and figured out what sizes i'd need for what was there (hitch parts, suspension parts, lugs, etc) and I just packed those. Screw driver (I just grabbed a multi-version). Drill. Pliers and vice grips. Thats really about it. I wanted to keep my tool collection from adding a ton into the rig!
