They are Rotopax containers. There are 2 - 2 gallon gas and 1 -4 gallon gas and then 2 - 2 gallon water packs. Here's a better shot. The GC had a 3" OME lift, BGF A/Ts and I swapped the wheels from the 18" factory limited package for the 6 spoke 17" Commander rims. It was a great vehicle and I really miss that Hemi!Really like the look of the Grand Cherokee! That's kind of what I'm going for. I already have the same rack and at some point will add the front brush guard. Question for you: what size gas cans and water cans do you have on the rack in the pic? I'm looking at various containers, but 50lbs of water and 40 lbs of gas seems pretty heavy to me. Maybe I'm worrying over nothing.
