Sloppy wiring etc. is just the tip of the iceberg for Airstream's lack of quality control IMO.
This site is full of similar reports -- read it and weep:
If the problem does not affect functionality, the best solution is to lower one's expectations, apply the needed patches and Bandaids, and go camping.
Or maybe write a book, with apologies to Robert Pirsig, entitled . . .
"Zen And The Art Of Airstream Maintenance"
PS -- Yes, of course, there are many happy stories of functional Airstreams supporting many joyous travels.
But the weak links in the QC chain are upsetting IMO.
