If you go to an automotive paint supplier e. g. Rare Spares they usually can look it up on their data base. Colours for cars, trucks, tractors and farm machinery, right back to vintage vehicle colours. These days if you have a sample it can be colour matched by computer. Good luck.
Why not just phone the Jayco factory and ask them.
Hello Gus yes I could do that but this forum lets me call on the experiences of people who have been there done that.. e.g. One chap was asking about bearings and asked a dealer but found the dealer didn't really know anything about it. I like to sniff around before i do things ya know... just saying.
