How level is your truck camper loaded?
How level is your truck camper loaded? For instance, if you measure from the bottom of the bumper on the far right and far left with nobody in the cab. I know a few people have stated they run d...

I once had contact with a VW vaganon user on the Samba forum.
He first gave the tires the same deflection ( measured middle of wheel to ground) and it gave ( by head ) RF45, LF 40, RR 50,LR 55psi, so crossed weightdifferences between the axles that you will see often when weighing per wheel(pair).
Then He leveled the car ( think putting wheelsheelds on same hight L/R, and then his tires where again different deflected.
Did not ask but assumed Front Right was lower and rear left lower to the ground, so it can even be different front and rear.
This gives torsion in the frame, wich compensated the real weightdifferences a bit.
By leveling these torsion forces where brougth backt to practically zerro and so the real weightdifferences came up wich deflected the heavy sides more.
So if you have some kind of leveling system , be ware that the needed pressure of tires must be higher.
In fact if you weighed you should reweigh when leveled, or level before weighing per wheel( pair) to have the real weights on seperate wheels at once.
Everywhere its written to keep the pressure Right and left the same.
Yustification for that can be that the mass on the axle gives equall sideward forces on R and L , so the stifness of sidewall has to be the same.
