I know I will be installing at least a 1" body lift when I finish the frame and tub repairs. Already ordered the ebay 20 gal poly tank but couldn't find a cheap skid. Already doing a ton of welding so I have a plasma and a flux core and stick welder. Can I just modify my current 15 gallon skid to place the new 20 gal poly tank 1" higher? Would really improve ground clearance.
