I am not sure I fully understood the warranty during my walk-thru but I seemed to get the impression that all the appliance-type things fall under that particular manufacturer's warranty and all the RoadTrek specific stuff would be covered under the 6-year. Things like cabinetry, flooring, etc.
My hunch is the awning might have been classified under the Fiamma warranty. If you "trust" the RoadTrek "chat" it is a very quick way to see what they say.....if they say it is under the 6-year you are prob good, if they say know you can ask a few more sources such as Fammia to see what they say as well? I have found their chat sessions very fast, friendly and correct when I used them.
