Water heaters

There's four 30 LB ers in what used to be the A/C condenser bay. The compartment door is 60 percent expanded metal - good ventilation. We have auto change over regulator with two tanks manifolded on each bank. Nice capacity and easy alternating fill with portability + the toad. Then there are two 20 LB ers for grilling +/or propane injection or can be manifolded on one of the change over banks. We started the conversion from an in service charter bus in 1979 and went with propane because of the frequency of boon docking. It has worked very well for lots of years without incident. We can + do go electric during shore power or Genny, including the 20 gal. Electric water heater.

Mine came with a 49 gallon propane tank mounted under the coach (about 210 lbs).
A bit of a hassle to fill, but with our usage, it lasts a really, really long time (over 2 years so far). Cooking & heating only, water heater is electric/ engine heated. We also have an electric cook top (gaggenau) that we like better than gas.

If one takes the time to learn & understand propane AND use it properly, it is as safe as anything else in an RV. In my opinion, definitely safer than lead-acid batteries. . . .

160lbs is a 40gal tank.

160 lbs may equal 40 gallons but in our "portable" case it's four 7-1/2 gal. & Two 5 gal tanks. Easy to fill remotely and bring back to bus...

I have a 20gal frame mounted propane tank. I fill it once a year.

We have a built in 30 gal and a 10 gal portable. We use propane a lot and still only fill the 10 about every 4-6 months. We keep the built in for a reserve in case we can't get the portable filled on time because we forgot about it. It's mounted in the forward bay in a boxed off cabinet and well vented through the floor. Easy to get in and out. If we didn't have the portable, I'd probably want a larger builtin tank so we wouldn't have to move just for propane. Course, by the time we went through the 30 we probably should be moving
