I took the van to Camping World in Sweedesboro,NJ where they charged me $95 to tell me there was an overflow valve underneath the vehicle and everything was alright. Next time I went to get propane, gas shot out from under the vehicle again, so everything was not alright. The question is, who does repairs to a propane system? The propane dealer doesn't, Camping World has proven incompetent on numerous occasions, nearest Airstream dealer is three hours away. Any ideas?
Actually, it may not be Camping World that's incompetent. It could be the fellow filling the tank.
There is in fact an overflow valve on the tank. Since the tank is built-in, you can't weigh the tank to tell if it's full. The usual procedure is to fill the tank until liquid propane starts coming out the overflow valve, then quickly remove the filler hose and close the overflow valve. Some
propane is lost, but it shouldn't be much, just a quick spurt. If you see a vast cloud of propane, that means he's leaving the filler hose connected too long. And incidentally charging you for all of the propane that's being released into the air through the overflow valve since it's metered at the pump, not at the tank.
The question is, when the guy is done filling the tank, what does the gauge on your control panel say? It should show over 75% full, and stay that way until you use up the propane. If the tank empties out by itself even when you're not using the propane, then
you have a leak.
