I was looking today at how the tank is mounted under the Blazer and it doesnt look to hard to mount it up higher. I have a body lift so I can get a good 3-4 inches up. Then I can pull the hitch tighter to the frame rails for better clearance in the rear. No I dont want to run a cell in the bed. I have thot about that and would like to do it but I would like to save the area behind the seat. I want to move the existing tank up. Has anyone done this, and if so what did it take and do you have pics? Looks to be just cutting out the crossmembers, and modifying the ends to move it up, and rolling the lip on the tank. And actually I dont think the lip will be a problem unless its right at the rail, otherwise it should go into the C channel of the rail. Am I way off base on this?
