Like the way it looks.

When ready for tires, stock size (rim width as well) and tire tread that essentially matches rim (published numbers) in an LT or XL tire would be my choice.

New shock absorbers as well as polyurethane anti-roll bar bushings. Transient response will be a bit tighter with ideal tire pressures (not overinflated).

I'd also check steering for dead center. A loaded -- wandering -- work truck really hurts itself due to worn componentry and load-induced alignment changes.

TIMBRENS might be good if wheelwell height measurements show up under a load. (What does that stuff weigh on a decent job? Or is it mainly the bulk involved?)
