"These guys at DRV DO read these Forums and maybe they took note that the rear cap on the lower level actually needs BACKING."
I was wondering about that. I wonder how many units were taken back to DRV for that repair. Ours wasn't done right at DRV but hopefully you're right Ron, that they sat up and took note.
REALLY glad to hear the positive results were achieved for your repair.
Using the wood backing will ensure NO more troubles in that area. Since fixing ours with wood backing we haven't had ANY issues.
