1977 Sovereign Belly Pan

Did the '77 Sovereign have an aluminum belly pan? I am looking at buying one as a parts trailer and was curious as this one does not have an aluminum belly pan. It looks like the frame and sub-flooring are exposed with some type of undercoating.

All Airstreams, ever built, have aluminum underbellys.

Thank, Andy. That is what I thought, but know I know for sure. Any suggestions on a good source for a roll of aluminum? I might try to fix it up after I take what I want, just doing some research.

I am finally getting around to fixing up the '77 and now see why the belly pan confused me at first look. The actual aluminum that is rear of the axles is just really corroded and looks to have some asphalt so it looked almost black in some areas at first glance. The tanks also hang below the center section of the belly pan, but are boxed in.

The other thing that threw me is that there seems to be a 2" piece of angle iron that is welded to the bottom of the main frame rails. This piece starts behind the axles and runs all the way to the bumper. Here are my questions.

1. Is the lower frame rail extension hanging below the belly pan factory?
2. Is this the same type of steal that the main frame rails are made out of.
3. I can see that the holding tanks sit lower than the center section of belly pan and are all boxed in. When did the AS trailers start having this design instead of the belly pan 100% covering the rails and the tanks?

It really threw me at first glance since the banana wraps butt up to that lower frame rail extension and then there is the center section of the banana wrap that sits in the middle of the lower extensions.

I would greatly appreciate some information on these lower frame rail extensions. I assume they were added to strengthen the home stretch and to help with rear sagging.

Hi there! This drawing might help you to better understand what's going on under there:



Here's one of the chassis too, just to put it in better focus:

Aage: This helps greatly! Now I can know what is factory. Do you by chance have the key to the second image? Are those pictures from the service manual?

Thank you,

Todd

Yes, they are both from the Service Manual, although I can't be sure what year; I have '77 and '74 Service Manuals, but I didn't label these images clearly to know which they are from.

Here is the text that went with the chassis, and it's similarly named, so tomorrow I will try to see if I can find my '77 one and compare to these then let you know.

I found this tank mounted directly behind the spare tire in a really nice galvanized metal box. Is this for a previous air/hydraulic brake system? The current brakes are electric, so just wondering if this was a factory option? Looks like it was installed in the past 15 years to me, but I am curious.

Old thread, but I'm sure someone will find this in their search as I have....I am doing a full monty on my 77 sovereign and I have the exact same air tank including identical box and straps. Since it is identical, I can only conclude that it is factory. My best wild guess is that it was used for air shocks some hoe (all that remains on my AS id the tank and some of the tubing) so I cant be sure.
