We (wife and I) do an enormous amount of primitive camping in the 4 corners area. We have a 2005 wrangler x running 31's. I built all the carry-all racks to my specific needs out of electrical EMT sweged and welded together. Everything behind the front seats is gone. I never believed a jeep should carry more than two people anyway. I even built a cantilevered front rack to spread the weight. We will stay out for 2-3 weeks at a time. The weight I need to carry is the only barrier for staying out longer. This past spring with all the provisions for 3-4 weeks, 10 gallons of gas, 15 gallons of water, a large water purifier + shower and potty, bear-proof containers, lines, pulleys, and hardware to raise the materials in the trees, onboard air, Tools and breakdown paraphernalia, two battery alternating system, wenches and lights and two 90 lb. Labs...we are near tweaked out. I need to increase the spring tension...not necessarily raise the vehicle. I would like to keep as low a center of gravity as possible. I would appreciate any help at all.

Thanks
