I removed almost everything from the RV that I had put in over time. I filled the FW tank. Then took a ride. I was able to identify a couple more noise makers and took care of them. One was a step stool that I thought was held tight by some foam but over time the foam compressed where it was tou hing the stool.
Today I put most of the stuff back in the RV storage compartments and refrigerator, etc. but in a different arrangement. I think I got lucky.
Took an 85 mile trip over familiar roads and it was a pleasure again. Very little noise and quite smooth most of the time. It must have sensed that we were looking at other RVs.
