[AT] Filling a LPG tractor

[Ray Trimble]

I have a MF 65 LPG. I have come to the conclusion I don't use it enough to
justify buying 100 or 150 gal at a time. I and thinking use 20# bottles to fill.
Has anyone done this, would I have to hang the bottle upside down to get the liquid
to come out?  What fittings would I have to buy?

Thanks

Ray
