Offroad trailer is the quickest and imo solution.
Sounds like you've got more stuff than I even. I had roofrack for years, loaded up family with gear for 3-4 day trips or my hunt camp, tons of stuff on the rack on top and the back trail rack with gas and such. Went through more shocks and springs than I can count. My good friend gave me an old trailer he made absolutley LOVE it.
I can email a pic or two of mine, there are a ton of others out there too if you know how to fab stuff.
Garage sale or junkyard an axle and build up or find old trailer and soup (not cooking liquid) up with spring over, tires etc etc.

Just my 2 pennies worth.
