I was looking at this option but it takes a lot of useable space out of the back of the truck(I only have a short box) If I needed to bug out I simply plan to throw 4 50L containers in the back with my other gear. The aux tank would be rather difficult to remove and replace for those times when I don't need it, such as hauling fire wood and hunting where I need all the space I can get. Thank for the link though, I actually found some other goodies I may purchase later.
