Used a lot of 2x2 1/4inch wall square tubing among other things and came up with something that" for lack of a better word" I call an inverted compression truss running the entire length of the trailer.
I hope this will completely eliminate the problems that the Airstream engineers so foolishly served up with their flimsy ass sheet metal piece of **** frame . After weeks of crawling around under the trailer and burning through about 15 pounds of rods with my 35 year old cracker box , I think I have recovered enough from all the pains and burns to think about taking some pics of the thing. and posting them on here for all to see and comment on my lack of welding and engineering skills. Hope it works anyhow, plan on heading up to Alaska with it next summer.
It sounds like you have patched and fixed the problem, as I have. Mine seems to be okay altho I don't like add-on patches. A whole new properly designed frame would give me much more confidence. BTW I hope you rebuilt all of the outriggers also. Mine all bent a while ago and have been replaced. I will never buy another 22'er. But I'm stuck with this one 'cuz it has little or no resale value.

OK , been trying for hours to get some pics loaded of the frame fix.
maybe I should get a seven year old to show me how to accomplish this feet !
what a bummer !

Thank you for the information Janet ! I shall make another feeble attempt
to get a picture to load up.
If it works, this is the right side looking forward from the front axle, shows some of the truss and braces to the outrigger and steps.

This one is the right side looking toward the rear. shows the bracing
to the outrigger and the rear truss . It has a 2inch wide 1/4 inch strap
welded to the main frame and outrigger , running down to the 2x2 1/4
inch tubing truss and the 4 inch wide 1/2 inch plate notched and welded
to the truss and outrigger. I know that some of the iron used in this project
is pretty much on the OMG that's too big scale , but I would rather have
too much support than put something under there that is like the wet noodle
frame that airstream designed . and the fact that this stuff came from my stack of stuff accumulated over way to many years .

This one shows the R Front axle mount --truss attachment area where the
4x4 3/16 square tube with the 2x2 1/4 inch tubing running through it is suspended below the axles with a u-bolt on the outside .
The axles act as very nice cross members for the truss and with part of the
weight of the trailer being applied to the axle tubing further out from the main frame the axles themselves will have gained strength from having less leverage at the fulcrum point.

this is the right rear of the trailer where the truss attaches to the frame.
The pretty , shining , aluminum , "bumper" has been replaced by a 4 inch channel iron . The frame and sewer hose compartment have been shortened a bit and a 1/2 inch 4 inch wide plate was welded to the side of the original frame and the channel iron . this allows the new truss clearance past the side of the poo tank. The truss is welded to the plate and channel iron.

This was all done while the trailer was supported from the rear under the skid brackets and under the front just rear of the tongue jack. this allowed the wet noodle airstream frame to have a slight sag in the middle instead of the ass end drooping. When the work was complete , the trailer maintains it's new stance while on it's tires traveling down the road.

It certainly is stronger than when it left the factory. What is irritating is that building a stronger frame would only cost Airstream about $250 to $300 more. If you figure about $1 per pound for steel and the cost for structural channel instead of "C" channel, the price isn't that high. Besides, the cost of the actual build doesn't change much at all. AS could use heavier axles and have much more payload. If they did this it would make their trailers more like the old Avion and Silver Streak trailers.

Maybe this topic has been brought up already? Axle spacing? The 22 CCD in comparison to the 25 CCD appear to be different in terms of axle spacing. The further the separation between tandem axles applies greater friction with tire scrubbing being transferred directly to the frame. Just grabbed two photos off the net that appear to show different spacing.

Why they do what they do in engineering the frames and axles on these newer Airstreams only the Good Lord above would know, but I bet old Wally is spinning in his grave !! You are absolutely correct that it would add very little to the initial cost to build a trailer that would hold up to years of of use instead of the crap they build now days ! And as to the distance between the axles, the 22 in my shop has a distance of 33 inches between the center of the spindles and with 235/75R15 tires has a space of 4.5 inches between the tires. That shot of the 22 probably has 14 inch tires and the 25 might be running 700/15s . that might be the optical effect of the axles being further apart ? These torsion axles might offer a bit softer ride than the short leaf spring set up, but the trade off is that the weight of the trailer is right on top of the axle mounts with the torsion axles and is spread out over a longer portion of the frame with a leaf springs set up . If it were up to me the way to go would be solid axles , but use LONG resilient leaf springs independent of one another for and aft and staggered so one could run along side of the other while maintaining proper close axle spacing. These springs would be about 6 ft long each and would allow the axles to move up and down a great deal more than they can with torsion or short leaf springs. The addition of an ample sway bar would take care of side sway created by using a softer suspension. Then you could use load range E tires with 80 pounds of air and still have a ride smoother than silk .
Ok then, nuff ramblin on about stuff that will never happen !! Happy New Year !

Here is a shot of the right rear axle area looking forward.

looking forward from behind the axles on right side
A rough estimate is that about 450 pounds of steel and rods were added to the total trailer weight doing this project.

from the front looking toward the rear on the right side

a tidbit of information was that the loons who built this thing at Airstream
left about 3 dozen sealer - caulk tube ends flopping around in the belly pans durn near caused a fire while doing this project. Thought about boxing them up and sending them to Airstreams president saying he should find a dark place to shove his trash !
