[HMayo]

Hi I'm Horace have a 2020 Keystone Montana.. I have a leak under the MW. Not therer while raining there hex try morningvat later. Is brown loe rust no warlter in me vent.. I also have a area on inside melow passenger side slide. Under smaller forward window. Not wet though after hard rain. What type of finish material is this seems rippled.

Horace, this particular forum is about molded (egg-type) fiberglass trailers like Scamp and Casita. Yours is made from laminated panels, which could be one of several different composite-type materials bonded under pressure to structural framing, insulation, and interior paneling. The rippling could indicate delamination, a common issue with laminated construction, though typically not on one so new. Molded trailers are not subject to this type of delamination.

You might get better help on a general RV forum such as iRV2.com. You'll find plenty of laminated trailers there and likely a few Keystone owners.
