Thanks alot for all the input. I didn't think they were made differently, but I thought it couldn't hurt to ask. As far as the gravity problem, I was going to leave it in the truck bed when fueling and just wheel it to the tailgate. I was hoping @4ft. would be high enough. 15 revs/gal with a crank hand pump is foolish IMO and would get old very quick. I didn't want to get the truck tank now just to have to switch it to the new truck next year. However that is sounding more and more like a better idea. Even a stationary tank in our garage doesn't sound like a bad idea. I just wasn't sure if that was a good way to go because our business is seasonal and the fuel would just be sitting collecting condinsation for @ 1/3 of the year in the winter.
