At their maximum 2.10" ride height setting, the front strut assemblies should still leave you with a bit of front rake (though not much). If your boat and/or camper are fairly heavy and stack on the tongue weight, then you could end up nose-high when loaded, which will throw off your headlight aim, but more importantly, can lead to stability issues. You could combat rear sag with a larger rear block, helper springs, or air springs. Unfortunately, the 5100 rear shocks aren't long enough to handle a 3" rear block or a 1.5" add-a-leaf kit. Your best bet would be to call us directly at 623-434-5277 so we can get more specific about your towing needs and possible solutions.
