spinbalance -- Your profile does not list an Airstream year or model. Frame strengthening is appropriate for the rear end separation years (wanting to say '70s into the early '80s but I'm a little rusty at this hour...).
Search the forums on rear end separation -- you'll get many hits and I know this repair has been mentioned before. IIRC it involves welding extra steel "sisters" on the outside of the main frame going aft from each wheelwell. You may find discussion of another type of repair by searching on elephant ear.
Please update your profile. It is not mandatory to fill in all fields but knowing your Airstream type may get you responses from owners similar to yourself. Congrats on your success in posting -- and welcome to the Forums!
This thread is the first (and only time) I have heard about a "Airstream Frame Strengthening Kit" for a rear bath trailer.
Where can I purchase one and what does the installation involve?
There is "no" kit that will straighten a frame.
There is a frame beef up kit, that only beefs up the frame at the axles. It again, does not straighten a frame, nor does it fix or eliminate rear end separation, nor will it prevent rear end separation.
Are there specific circumstances/models/lengths where you see the kit being used effectively.
I have not seen any effective use for the frame beef up kit, except when someone wants to grossly overload the trailer, ignore the fact that the trailer has bad axles, and doesn't believe in "PM."
Correcting the problem after the fact is expensive.
Balancing the running gear, in comparison, is very cheap.
We had frame stiffener/strengther done in 2002 North Dallas RV
972-242-0404. If you have a 70's model with rear bath you need it done.
Rear end droop is a major problem as the bread company that owned Airstream in that time period added the rear bath without improving the frame
to handle the weight. No holes in this doughnut.
WE have 27' 2 double beds w/rear bath. We got rid of the kids so we wouldn't have to put up with them needing to go pee just as we snugled up for the night. Now all we have is Chigger Chihuahua, Norie Joe Norwich Terrier,and Houdinie Budgie. None of them care how we sleep and none of them use our toliet . No really rear bath is not the best idea for family travel, but I love the big wardrobe & dresser in my bedroom. I found no problem with the sink/ tub area. I took down the original heavy wooden doors between bedroom and bath put a metal channel above the door, installed a cheap expansion shower rod over tub so I could angle it over the mirror to fit snug not tight . Also attached a cheap plastic neck tie hanger to the old door frame on bath side about mid way between ceiling and floor . Then I bought a decorative shower curtain and some cute shower curtain hooks . I arranged the curtain and hooks so that they were in track over bedroom door and the rod over tub .The tie hook is used as a tie back when curtain not in use. No more rotted door, less weight on rear of trailer, and solves shower door problem all for about $45.00.
Lady Penelope, my other half, wanted to change our layout. From rear bath to center bath, with rear bedroom.
I started to list everything that need to be done and came back to her, pretty soon actually, with those words "no".
Too much to do. And especially about the water heater, to move it you need to do an opening and close the old one, and black water tank. That was my major concern, not too worry about the plumbling and everything else.
I wouldn't go with that.
