I've been thinking of upgrading my 845 lance camper to one with a slide. Preferably a 971 or similar dry bath camper. How stable are the srw trucks with the additional weight?
"That is why heavier diesel will have lower cargo rating as nobody wants to pay registration for what the truck can actually handle."
I always assumed it has less payload because the diesel is so much heavier. GVW-actual weight=payload Not every state has expensive registration costs.
