1970 overlander frame separation - when to repair?
I'm a new airstream owner as of August (27 ft overlander, 1970, rear bath, twin beds). I happened to have bought my Airstream mostly sight unseen, which is not a good idea, but wouldn't have known to inspect for frame separation at the time anyway.
Thanks to the forum, I've done dozens of repairs - new plumbing, lots of new weatherstripping, lots of cleaning, , re-hung the main door (drill the holes out a bit for more adjustment range), etc.
My goal is to use it next May - I plan to replace the axles before then, as they are shot.
My question is - is approximately 1/2 to 3/4 inch separation at the rear most point in the frame "too much" for in-state travel (~150 miles each way) on smooth roads with new axles, no overloading (maybe remove battery), and balanced running gear?
When I stand on the bumper, I appear to get another 3/8 to 1/2 inch travel (if I bounce up and down a bit).
There doesn't seem to be any evidence of body sag - the side panels and wheel well areas are straight and solid.
I basically want to divide repair of systems up in such a way that I can operate the trailer for a few seasons of relatively easy use now.
Does this make sense?
Pictures are in my airforums album - I'll see if I can post one here later.
