1 four wheeler in the bed and 2 on the trailer along with 4 dirt bikes probably my heaviest... I've hauled alot of mulch and lumber with mine. I rebuilt the deck at my house, 158 boards is what it took. I took em from lowes to home and the old ones from home to the dump.
In the bed, I hauled a half a load of firewood across the yard. The largest trailer was an empty 16'. Ive also towed my 5x10 trailer with a 4 wheeler a few times and once with a load of firewood. I really didnt buy the truck to haul anything. I used to have a 2500 that I used for hauling and towing. Now I usually just use my wife's Tahoe or borrow a truck from my father-in-law if I need to tow or haul.
Im like Honeycutting, I should have bought a blazer because I dont halu much in the bed of my truck. I bought mine mainly to squeeze into the woods and sneak up on critters. I would have bought a BlaZeR2, but the thought of a dead deer or hog in the back just makes no sense. Plus the camper on the back kinda restricts what I can put in it anyway.
