Seriously? You're dragging a camper and a dirt bike! You so carry everything with you!
Here is mine, weighed as stated previously. No kitchen sink. My overall weight was way less than your contraption.
Add in a custom fiberglass pop-top, 5x 35" tires and wheels, heavy duty aftermarket axles, knuckles, steering, control arms etc, steel bumper, winch, arb compressor, heavy duty driveshafts, rod ends, it all adds up. Hi lift, snatch block, straps, tools, a few spares. Camping trips included a cooler, stove, 8 gallons of water, 2 gallons of gas, sleeping bags, cooking gear and food, photo gear.
