As always a bit more travel wouldn't hurt.
I guess there is 2 ways to do this; 1-longer travel shocks. or 2- lift kit.
I'm guessing lift kit simply because by the time you add a camper trailer, all your gear plus who ever else wants to tag along there is a fair bit of weight on the stock springs.
So whats everyone else done? with 33inch tires. Whats legal?
