Sure, you can tear up ground with 4x4 as well. But, if you had been here, you would see the damage that didn’t happen because of 4x4.
You meant 2X4 didn't you,one tire in the front pulling and one tire in the rear pushing?(Laughing)
Lockers on a 2WD DRW give you 4 wheels pushing or 4WD..
I think most of us realize any pickup with a full sized 8ft wide(13ft high) truck camper is not an off road,like in true 4X4ing,rig..To high/to heavy and to wide..So it is "very limited" where it can go, 4X4 or 2X4..The narrower and the least tall definitely has the advantage,like the pop-up truck campers.
Take the 10ft plus truck campers with a slide,where are you really going to take that big/heavy/wide beast?..Kayteg showed he can take his Lance 1172 up a pretty narky road for such a large truck camper but I'll bet he is the exception,not the norm..And he did not need 4X4 to do it,just RWD.
As for real off road 4X4ing..I have a Yamaha Rhino with 2WD/4WD and 4WD lockers where power is to all 4 wheels..It's narrow and can get where Jeeps, like the CJ5 can't and can carry 500 pounds and tow over 1200# with two peoplein the front.
So most of us have a truck camper because we tow our toys, whether it is a boat/jeep or ATV's so we do not need to take the TC back into places that can damage either the truck or camper because of it's total weight/width or height,so 4X4 is not needed..JMHO
