Holey Gawd, just thinking about a cross country trip with that 401 gets you to hyperventilating... My 305 v6 burns fuel like a space shuttle (and that's even when it's *NOT* on fire

) -- I can't imagine one of the bigger ones...
Back to the OP ...
Have we figured this out yet? I'm waiting for my welder to tell me if the pump on my truck is scrap metal or repairable. If the former, I'm thinking of removing the tanker body and replacing with a dumping flatbed with a flip ball hitch for a gooseneck. We could get even crazier and shorten the frame to make a duallie pickup out of it... Several ideas in play ...
