I have two places near me where one charges by the gas required to fill the tank and the other a flat rate. You can guess which one I use.
For the water heater, keep in mind that the tank will not run all the time. I recall one poster, Bruce I think, that says the pilot really maintains a very good level of heat which would extend the usage time.
And as I plan on doing with my 6 gal. Suburban Heater, is to add even more insulation around it. Every little bit has to help.
I've owned RVs for over 50yrs. We learned very quickly that a water heater is usually a 'propane hog' if you use it to maintain 'hot' water normally. I discovered that once I set up camp & turn on/light the water heater, when it finishes the first heat cycle. turn the control down to 'pilot only'. The pilot will maintain a hot temperature for days unless you empty the hot water tank, or nearly so. For normal morning face wash, doing dishes, & such the pilot light alone has kept us in hot water for days, even when temps fall into the mid-40s at night. This has worked well in smaller, 18' trailers & large cabover campers. If you use the water heater for showers'n such, dunno how it'd work but I expect it wouldn't 'keep up' with demand...
