Ask anyone who knows me and they will gladly tell you what a ridiculous amount of junk I can and often do fit in a Jeep. I once had the bed of a long-bed Ram filled, and got all the stuff into my XJ.
The day I was bringing down property values, I got the lowering kit, the TEK 4 tools, and some other stuff for Randy into the Jeep. But that didn't compare to the five 33-inch tires on Dick Cepek DC-3 wheels and the five 16.5-inch 12-bolt HMMWV rims I jammed in it yesterday. Good thing my bastard leaf uses metric tonne MJ springs.
And why not take the 715 in the background? Well, 500 miles in two days in the XJ means decent highway speeds and 30 gallons of gas. 500 miles in the 715 means about 50 gallons of gas, and top speeds of 60 mph. Well, that, and I always think "no problem" to fitting things into the Jeep.
