As often as Jayco changes things I would email them your VIN and ask what brand of caulk they used. When I asked they told me QUAD caulk which is available at Home Depot in many colors, yours may be different.
Thank you I will do that. Can't say that I've ever heard of QUAD brand caulking, but I guess I'll find out. I don't want to mix incompatible caulks. Trying for the exact same color as well. Yes They have it at Home Depot, I just looked on the web.
