Sorry if this is a belated reply, re Dave and LJ's and finding another business to do interior work.
We have not used anybody since our experience at Dave and LJ's. We have had some chassis work done at OMC in Eugene and also at a private shop in Junction City, OR.
Maybe we can meet for coffee sometime and put heads together?
I used to live in the Longview/Kelso area and am now south of Kalama.
Wish I could have helped you more. I usually do my own work on our coach, FYI.
