.....anyone ever do it ?

The ONE major complaint I have with this Airstream is the small tank. Can’t do much with the length ... but could probably go with something 6-8 inch larger in diameter...

Doug .... how does that work rolling down the road ? NOW IF all I had to worry about was powering the frig and stove with LP .... no problem. But the gen is fueled by LP. And that consumes lots. Heating? .. don’t use that much at all but if you did ... you’d have to get the tank filled quite often !

To use a larger tank (I'd suggest a 50 it is easier to carry)
You use the on board tank on the road
you use the "External" when parked.

Done that with my class A. it had a 100 pound on board (27 gallons) and I used 20 pounders when needed but.... It was nice when I could not get to ye old propane place.


Home was where I park it. but alas the.

In addition to our onboard 100 lb ASME tank, we carry a 30 lb DOT cylinder connected to an Extend-A-Stay fitting. Under way, the cylinder is secured in a ventilated storage bin with the Extend-A-Stay hose attached and active. Most of the time we only switch to the 100 lb tank until we can get the 30 lb cylinder refilled when it runs out. It's usually a lot easier to get the portable 30 lb refilled than the onboard 100 lb tank.

You have found the BIG problem when OEM's use LP powered Gensets versus spending the money on a Diesel genset on a Diesel powered Motorhome. Since your handle states Land Yacht, I will bet you have a 1990 to 1995 or so Land Yacht Diesel. Back then, Diesel RV Gensets were very expensive and OEM's installed LP powered Gensets to lower the cost. Also, some models of Diesel Motorhomes could not be configured with the size and design of that era Diesel Gensets. Some older Airstreams(1980 to about 1985) motorhomes, not Land Yachts, had 2 ASME LP tanks. A LARGE tank that held about 28 gallons liquid LP on the drivers side and a smaller tank about 10 gallons on the passenger side. The large tank powered the LP genset. FYI, these Airstreams used a Isuzu Diesel engine on a Chevy chassis. So, the Extend a stay ONLY works when camped. Then you have to have a way to safely transport the cylinder. ANY type ASME tank you will be able to find that will be larger will probably only increase your LP by at most 10 gallons. Not feasable for the cost. Doug

LP powered generators have caught a lot of diesel RV owners off guard. Manufacturers still opt for the cheaper installation unless the customer specifies a diesel generator. Especially in the smaller RV sizes.

I will tell you, when a customer wanted to trade a Diesel Motorhome with a LP Genset, the trade was downgraded from 5k to 7k in price due to the LP genset. This is one upgrade that will help pay for itself. Doug
