I got the 90gal RDS fuel tank/tool box combo for about 550 over two years ago. Very nice aluminum tank. All together with shipping, tank, pump, filter & plumbing would have been around 800 bucks. Since I live in the cold I had to upgrade the transfer lines to arctic grade hoses (very spendy). I also installed a fuel level sender & auto meter gauge in the cab. Its been worth it. I can make it all the way thru Canada with 115gals useable.
