Suspension mods

This all depends what you're comfortable with. I started out hauling firewood stacked to the roof in old trucks that you hoped the tires didn't pop. Turned wrenches and hauled a lot of materials for a landscape co in my teens that would give most on here an instant heart attack. Welded up truck frames when the workers would overload them so bad the frame would split over the rear axle! Twisting off driveshafts, rebuilding axles annually or more, etc. they weren't always the right tool for the job, but I learned well what the physical limits of trucks were.
I don't look the same at 1000lb "overweight" as most.
Btw my wife is totally comfortable driving the truck/camper too, so it ain't that bad!
