RE: Filling large propane tank on the road

And FWIW - the rate of propane usage is not linear due to the shape of the tank, assuming your tank is primarily round and is laying on its round side like most fixed tanks are mounted. Some portable tanks are filled standing up, but are installed laying on their round side. The lack of linearity is due to the circumference of the tank. For example, the gauge will move slower the closer the liquid fill level is to the center of the tank. As the liquid level falls from “full” to closer to centers, the gauge moves faster than it does going thru the center liquid fill level of the tank. And as the liquid level starts falling below the center of the tank, the rate of gauge change starts increasing again.

RE: Filling large propane tank on the road

OK, update. I did get the tank filled at CG yesterday on our way out. Figured 24 gal tank and gauge showed 41% and needed to get to 85%, so my limited math skills said I needed about 12 gal. +/- or so. In a hurry blocking exit to CG and guy filled it with 17 gal saying I must have been on empty....didn't look at gauge until I got to next stop, and sure enough, gauge shows 96% full. To get rid of some propane, I am using propane hot water heater, but don't think that will "bleed" off excess propane anytime soon. Should I worry about 96% fill on tank? .8 x 24 = 19.2 gallons. If he put 17 in, you must have 2.2 gallons in the tank. There is a valve in the tank that prevents filling above 80% (unless you have an ancient tank). The monitor inside your coach 99% of the time is driven off the tank gauge. So if one is wrong, the other is likely wrong unless there is a calibration setup that allows the monitor to read full at 80% fill (which is a true reading of tank capacity).

RE: Filling large propane tank on the road

FWIW - We’re in Dallas, and the Tractor Supply’s around here will not fill permanent tanks in a motorhome. I’m not sure any of the, will - YMMV, but I would recommend calling first. We have found the Pilot station in Waco to have the best price on propane. Pilot does somewhat cater to the motorhome’er’s, but as previously stated, not,all Pilot stations carry propane. There is a propane dealer in Forney, Tx, right on the Hwy 80 west bound service road, who services motorhomes. A lot but not all motorhome/rv dealers sell propane. But a key thing to remember - you have to ask or make it clear that you have a permanent tank in your motorhome unless you do as suggested and have the modification done where you can connect one of the bbq grill style bottles (but keep in mind, I am pretty certain it is unlawful to carry one of those bottles inside the coach when underway).
