Upgrade to larger propane tank on 07 Airstream Interstate

I'm going to say I doubt it, but like Davydd said just get under it and see if the 30 tank will fit.
Manchester only makes 2 Horizontal ASME tanks, a 20, and 30 lb.
Here is the link to their web site, and specs.

You guys are confusing the issue. The OP has an Airstream Interstate Sprinter Class B van. Airstream still makes the Interstate Sprinter Class B van.

Option7,

You could visit an Airstream interstate dealer and ask them if they have a solution. But the first thing you can do is research the possible standard tank sizes, get a tape measure, look under your van where your propane tank is and determine yourself if you have the extra space to install a new, larger tank. If you think you do, then find someone that can do the work. It could be an Airstream dealer or it could be an RV service center with the capability. A tank is a tank. Just duplicate the connections you have that are outside the tank.

I would contact Airstream first. One thing you do have to consider is weight. You can investigate that yourself but Airstream might already have a ready answer for why they put in such a small size propane tank and also whether they had a larger option. You are dealing with weight limits and weight balance as well. If you have an NCV3 Sprinter model (6 cylinder) and only a 2500 chassis (4 wheels) the small tank might have been a concession Airstream made to build on that chassis initially. Everyone finally bit the bullet and went to the 3500 dually chassis. If you have a T1N chassis (5 cylinder models) it was also a 2500 but toward the end of that model run converters were pushing the weight limits on them as well.

Good catch. I keep think about the Airstream land yacht motorhome of years gone by.

Airstream is still in business but they no longer build motorhomes.

While Airstream does indeed still build trailers, they apparently do still build some coaches. See here..

Folks can debate whether they're "B"s, or something else, but they do still build 'em.

Cheers.

The best place to inquire would be at www.airforums.com
