[Jack in Alaska]

My 2004 Dodge dually 4x4 weighs in at 10,000 lbs. fueled and ready to hook-up and tow.
I carry 45 extra gals of fuel, 1 gal ea. of antifreeze & fuel conditioner, 1 qt. of oil, tranny fluid, diff. fluid & x-fer case fluid. 2 sets of tires chains, shovel, 3000 watt Yamaha gen., 12 ton bottle jack, tire irons. various hand tools, flares, 30' one inch tow rope with chain ends, an extra unmounted truck tire and warm clothes.
Traveling the Alaska Hyw in early winter and late winter we need all of that stuff for safety.
I carry an eight foot aluminum ladder on my rear RV ladder. Also an extra unmounted trailer tire in the storage compartment.
You can always get a tire mounted at a reasonable price but buying one on the Ak. Hyw. can be a real pricey situation.
