I had a 2wd pickup that I kept an inner tube filled with sand in the bed. Never needed the sand but the extra weight helped a lot.

Cooper ATX, 275-70-R17s on Hawk shell on a Tundra

 

 

 

I run 45/50 front/rear on the highway, and 25/30 on rocky and washboard roads. Frankly, I notice way less difference than I would imagine. The number were the recommendation from the off-road shop who installed the rims and tires.

 

I wouldn't go as low as the 15-20 psi minimum which the off-road place suggested other folks go to...with the camper on...because, well, the camper weighs a thousand pounds.

 

Good luck, and keep us posted!

When I go 15-18 lbs, it's only in really soft stuff for short distance and at low speed.  Usually not more than 1/4 mile from camp to beach and back.  Never had a problem with that with my 3/4 ton Dodge and Grandby.  At 45lbs I never drive over 45 mph on the E rated tires.  In Baja I would drive from Los Frailes to La Rebira  (20 miles with 10 being washboard and 10 pavement) and then pay the llantera to fill up the air to 65F and 75R for the highway.
