Thanks all for the replies. I got weighed yesterday, front axle 3620, rear axle 8680. We're about 1750 lbs under the gvwr, this is with a full water tank, full gas tank and all the gear we usually haul with.
Based on the Goodyear chart I can reduce tire pressures a bit, to ~55lbs front, ~70lbs on the rears. I will check with Goodrich though.
