From the Lifetime site: trailer weighs about 700lbs, the tent weighs 25lbs. I figure the tool box and battery setup probably weigh a combined 80-100lbs. Load on all the gear, I am probably sitting somewhere in the 1300-1500lb range. Once I add the bigger axle and tires, figure another 100-125lbs. Not bad at all. I got 12mpg heading down there, 13.5mpg on the way back, and I averaged 6.8mpg on the trail...lol.
