Our trusty family Xterra (2wd) will soon become "my" truck when the wife gets a new ride, so it will see a lot of motorcycle hitch carrier duty (at least once a week, often more) and in the summer it will serve as the tow vehicle for our boat (roughly 3500lbs). The hitch carrier and dirt bike is probably 250-270 pounds. I think the springs are fine, as the truck does not show any excessive sag with the boat or carrier, but the stock shocks are DEFINITELY not controlling the load. What are the best options for new shocks? I have always had good luck with KYB products, and they have the gas-adjust model that is supposed to be an upgrade. A lot of folks seem to like Bilstein shocks. The only adjustable shock I see is the Rancho, but that's probably overkill for my application. What do you guys think?
