I seem to have fixed it.
A more careful look under hi-magnification revealed ring cracks around =20
HOT pins especially,the STR30130, relay, and to lesser amounts numerous=20
places. I just swept the board, and it is stable now.
Eric Manual was nice enough to send a schemo file of a similar model.=20
Thanks to all.
The RV and the highway seemed to have done the damage.
