I carry an upper radiator hose (can be shortened to fit lower if need be), a serpentine belt (can be one you replaced earlier because it started squealing), full set of Craftsman screwdrivers, 5 different types of pliers (diagonals, linesman, slipjoint, needlenose, regular), rivetgun w/5 sizes of rivets, all kinds of fuses for trailer and truck, extra Quest/Pex water tubing/fittings, folding shovel, tow strap, 200 psi air pump (12 v.), bungie cords, rope, 3 sizes of electrical wire in 25 ft. lengths, extra battery charger/maintainer and a compass (military/tritium). I leave the house with two-four 2 litre soft drink bottles that have been filled with water and frozen. By the time I get to my first destination, the frig and contents are cool and I can fire up the propane frig. I then move the frozen bottles into the freezer if I'll be on the road the next day (110 v./propane frig). This gives me a source of cold water to drink or for the radiator if I need it in addition to the 5 gal. and 2 gal. fresh water containers I also carry. I also have a couple full MRE's, at least 10 brownies/snackcakes and 20 packets of Koolaid from MRE's. I've probably forgotten something. I use to carry an extra qt. of oil but quit that years ago. I do run synthetics but if a synthetic oil is not available I can use a compatible dino oil if need be.
