If this is a work truck with widely changing loads - I'd say Rancho 9000's. You can dial in the exact damping for smooth highway, two track or a heavy tall load. I've used them over the last 30 years on my trucks. Guaranteed for life (if you keep the original reciept), good luck getting any type of adjustment with Bilstiens. Never had one leak, squeak, rip, rattle or tear. Each set got at least 200k miles on them before the truck left.
I moved a very heavy water logged wooden framed camper once. The truck couldn't go over 45 mph without bobbing and weaving dangerously. I stopped and dialed up the Ranchos a little and it handled like a sports car.
Good and Cheap shocks.
