That all makes sense.
A close friend was the Lance Dist here in Utah for many many years, I trust him more than anyone else.
He sat in many meetings where Ford and Lance engineers discussed truck "real world" capabilities. There's a larger safety margin built into trucks and tires than people realize.
I am over weight a tad and he told me not to worry about it.
If I was over weight enough for it to cause problems or be a safety issue he would be the first one to tell me so.
I bought my current camper back in July. I did the walk thru with him on the phone. He knew exactly what I was buying and the truck I was going to carry it with. He reassured me I was OK.
