Adding/understanding Propane Capacity

Considering a move from TT to Class A '08 Southwind 32VS Whorse 8.1. Propane capacity of 25gal. How does that equate to (2) 20# tanks? See some A ads with 80 gal. Great info on this site. Thank you, Rick

Propane weighs about 4.4 #s/gal so 25 gallons would weigh approx. 110#'s.

A 20# tank has about 4.55 gallons.

Our tank is a 40 gallon/32 usable so it should weigh about 141#'s when full although it's welded to the MH frame so no way to weigh it. Luckily, here in WA they have to, by law, use a pump with a temperature/pressure compensating meter.

Unless you're looking at a Newell/Prevost MH I doubt that they have 80 gallons of propane. And in those units there may be no propane at all as a lot of them were built as all electric units.

If the tank capacity is 25 gals., the propane capacity is 20 gals.
The tank can only be filled to 80% of the tank capacity. Like MrD said, propane weighs 4.4 #/gal.

OP posted that the tank capacity was 25 gallons so I assumed that it was a 30 gallon (or so) filled with 25. You might be right but no way to tell til the OP comes back and corrects it.

Capacity Should Be Ok

The 25gal appeared to come from mfg data so with the info you all provided we should be fine. Many thanks. Travel safe, R

Here's the brochure for the '08 Southwind (BTW, the 32V is one of my favorite models).

http://fleetwoodrv.com/frvlibrary/do.../2008_sw_b.pdf

The fine print states it has a 25 gallon tank, but only can be filled to 80% of that value (or 20 gallons).
