I could probably take the tranny out of his burban, and put a new one in in the amount of time it takes to get the tank down, if you plan to re-use the tank....
True.
The best way I have found is to use a couple ratchet straps hooked to the frame to lower/raise the tank. Still not easy but you aint gotta worry about that big tanks sliping off the jack when your working with the hoses.
