Man, this thread makes me really happy... when I started my MH search a couple years ago I joined another forum (that will remain nameless) asking for advice, and the sentiment was "Don't bother with anything older than 10 years." Well, I wasn't interested in spending thirty or forty grand on a toy, but it did make me feel poorly about what result my money was actually going to get.
I ended up with a '93 Southwind 30E, probably identical to the OP's, and I love it. Then I found you guys, and I love you too!
The only issues the Southwind has suffered have been totally minor, not even worth worrying about. All the big stuff - the electrical system, plumbing, drivetrain, has been flawless and a pleasure to operate. The '90s were a good time for GM mechanicals and it shows even in a motorhome - a strong engine and a perfectly behaved transmission. I also like the narrower footprint of the older models, and since I'm more interested in just a travelling bathroom than an actual travelling house I appreciate the simplicity of no slides and such. The Southwind is a mobile bed & bath for us, not so much a mobile home.
I do foresee a time in the future when the electrical system is going to give unexpected problems - I am *shocked* at what a poor job Fleetwood did - unprotected terminals and non-weather-proof connectors everywhere. I've done a bunch of upgrades on the electrical system, and each time I do something I end up spending an extra hour or two cutting back corroded wires or terminals or connectors and replacing them with proper, automotive-grade parts. I've spend a relative fortune on marine-grade heat shrink, Permaseal hardware, and Weatherpack terminals, but hopefully the long-term result is worth it.
On the upside, I'm keeping a great old rig running great and satiating my OCD at the same time.
I just redid the battery cables, and even walking by the front of the thing makes me feel good.

Still got more work to do up there, but the foundation is solid.
