I own a 2006 Jeep Wrangler Unlimited. I sometimes tow a small Tent trailer(about 1200 lbs.) When I have it fully loaded my wrangler squats alot in the rear. I need some ideas on upgrades to help level it out. I have no lift and factory shocks. I've been looking at Skyjacker Nitro 8000, Rough Country 9000 etc. will these do the trick? I need some ideas!!!8)
