Weight on tires, one heavy diagonal, one light diagonal
I finally weighed my 2015 F350 SRW + NLE 9'6" QSE wet + mostly full, and the results were interesting.
Let me start with a prior observation that seems relevant. I unloaded the camper on a very level surface, and the ruler on each jack leg read the same, say 24" off the ground. Despite being equal, I discovered one jack foot off the ground, which made me realize most of the camper weight was probably on a diagonal, like / (i.e. driver-rear and passanger-front legs carrying most of the load) or \.
To my weighing session on an Oregon Department of Transportation scale. First, those scales only accomodate one axle, and I could get up to 400-lbs of variability off the 1-tire and both-axle-tires weigh attempts, depending on where I parked on the steel plate :-( The "x" numbers represent average weigh results, and all other numbers are additions or sticker limits.
FL 1950x ... FR 2275x ... 4450x front total, 5200 GAWR, 3640 tire rating
RL 3500x ... RR 3050x ... 6450x rear total, 7000 GAWR, 3640 tire rating
-------------------------------------------------------------------------
.L 5450. ... .R 5325. ... 10900 total, 11000 GVWR
The upshot is, even with a little more weight expected: am ok on GAWR, the rear-left (RL) tire is near its limit, and a little over on GVWR. It is beyond me how this camper is marketed for 3/4 tons.
Now the question - note how the RL and FR tires on the / diagonal are heavy, and the \ tires are light. Like my camper on the jack legs, are my RL and FR tires carrying more load than they should? Can I raise the \ tires somehow so they carry more load?
I haven't yet checked if the camper tilts left or right. I'm anxiouos to do a weigh session without the camper to see if the truck has odd diagonal weights. When I installed stableloads, I only inserted 2 of 3 wedges, and wonder if I can add the 3rd wedge to the RR tire.
