You do not need a "Uhaul tank". They will fill any modern one.
A typical 20 lb tank holds about 4.73 gallons, so that comes out to about 4.23 lbs/gallon.
It might pay to check Uhaul's website for propane prices before going. The two stores closest to me have significantly different prices (one is 50% higher than the other).
Also, any gas station with a big propane tank outside can refill it. I tried calling around, but Uhaul was still the cheapest.
