Are you seeing bubbles or just some soft caulking under the edge where the roofing material rolls down the side?
My TT has an ugly roof edge. If I go up on a ladder and press on the edge it's squishy. They put a soft caulk? on the edge for protection when laying the roof.
Different strokes for different manufactures. Knowing how Lance builds their TT's I'm surprised that it looks like that. In the past they had one of the cleanest looking exteriors on the market for TT's. Some changes were made to the 2022's and they were bought out by REV Group so it's possible that QC and costs has changed the finished product some. I believe they went with a new roofing material for the new 2022's.
