Question...how do they fill a permanently mounted tank. When I fill my tank, I just take it out and they put it on the scales and fill it. How do they judge the amount?
I'm not sure if an LP station will fill your tank if it's inside the living area. No matter how well the locker is sealed and even with vents/access hatches. Ask local station propane dealer about that.
To fill a permanently mounted tank (and why we have had the one on the Class C filled once). You pull the RV up to the propane filling station. You turn everything off (engine, generators, gas appliances). The filling station fills the permanently mounted tank just like they do a big tank.
, the permanently mounted tanks are a PITA. We started full-timing again in 2006 (been "camping" since 1979). Our first long term stay (State Park in S GA) was for 3 or 4 months and we had a propane filling station at a convenience store at the entrance to the park we were staying in. We also had several 20# LP tanks and carried two with us (at the time we had 10 20# LP tanks... we are now down to 5). We didn't want to fill the permanent mount tank because we knew what was involved (break camp). We hit every LP fill station, including a dealer to fill our little tanks. $25 was NOT a good price. We ended up going the Home Depot where they had an Amerigas tank swap for $15. Generally we refill the tanks because it's cheaper to refill rather than swap. But we do swap out tanks when one starts getting "bad" looking or when the tank expiration date starts getting close. We do watch the condition and tank date when we swap out. Back when the "old style" POLs were being phased out, we swapped all our little tanks for the new POLs. It was worth the little extra price. We also swap out tanks when the LP filling stations are closed (here they are closed from 5PM on Friday and open the following Monday at 8AM). Currently a tank swap is running about $23. To refill the same size tank cost us $14.98 including tax on Thursday. We will be using 20# LP tanks on the bus (two on an automatic changeover valve plus 1 as an extra tank). We will build another "extend-a-stay" which will allow us to use a 100# tank if we want and to also run our BBQ grill.
FYI: The places that will swap a 30# tank are few and far between. You can refill them but a swap is generally out of the question. So for full-timing/traveling that is not really a good idea unless you are carrying a 20# tank just for that. If you are never going to full-time or "long-time" (a couple months at a time rather than 24/7/365), then it is not really an issue. We were getting tanks filled in the campgrounds in TX. The big bottle trucks drove thru and made deliveries... you just set you tank at the end of your site or flagged them down to fill the permanent tanks). Slightly more than hauling the tank in to fill but only a dollar or so. We didn't have it done because we left NM with a full permanent tank PLUS 2 full 20LB tanks. That fuel lasted us from Nov to June. Electric was cheaper than LP. Word on the RV forums is that this practice is being regulated out. Reasons vary, either city government or insurance reasons have been cited.
