More obscure items:

Welder (the biggest 110V MIG welder you can find)
Angle grinder
Pop rivets
oil drain pan
safety glasses
variety of funnels
hand cleaner (combined with the weed sprayer recommended by IdahoRob)
Spray-on degreaser (also use with weed sprayer)
Weather station (at least get a cheapo unit that displays temp, humidity and barometric pressure)
EZ-up canopy, for sun or rain
Several gallon jugs of water, to hold down the EZ-up, and to drink or clean with as the weekend goes on. And for refilling the 6.0L after it pukes
