So when I bought my 40, I had no idea what I wanted to do with it, I just knew wanted it, or should I say wanted one. I have decided to make my rig a little more trail capable and one of the components I will need to add is a traction / wrap bar to keep my rear leaf springs in shape. I have an '80 40 with the tank under the body which will not allow me to make a crossmember to mount a traction bar to. I have put in a couple of hours of research into auxillary tanks, and alternative tanks both here on MUD and also on Pirate. The only options I have found are the Con-fer tank ($$$$$) and a mid 90's s-10 blazer tank that mounts between the frame rails in the rear. Both of these options hang I think 6-8 inches below the frame and would require some type of skid plate for protection. I just wanted to throw this out there to see if anyone has any experience with another type of tank or has any other knowledge they have been storing up in their dome that they are willing to drop at this time. Thanks, Evan Edit: I plan on extending my wheelbase in the rear, which is why I am trying to find other options for tanks. From what I have read, rear tanks will not work if you extend your wheelbase.
