Not to sound thick headed, I understand they don’t shift weight, they do more than change angle of the body though when your suspension is tired and worn. They support the load but do not distribute it. Yes I am aware that they lift weight off without having weight distribution used at the same time.
Now the question concerning your advice is” will it mess with the WD inflating AFTER setting bars for level”. It seems the geometry and height measurements would change considerably. Making me again completely set the hitch back up.
When I said earlier that I aired the bags before connecting the bars it was added before even hitching. The 15 psi mentioned put me at factory height according to what was written by trucks PO in the owners manual.
Fuel tank is on drivers side. This might account for passenger side being weaker since most manufacturers design into the suspension extra lift for the side with fuel tank. There are two diaper bags and a camper top on the truck at the time of measuring. Concrete sacks are used to simulate weight of equipment and people when I set up fully after getting front air bags in.
