Hmmmmm. OK.
If no one has any idea on here, you could try asking on the Yahoo Roadtrek Group, or maybe on the
RVNET forums. Someone there might know.
Or, if you're in no real hurry, send
service@roadtrek.com an email, and include your VIN number.
It might be a few days before you get a reply, but they'll know where it goes.
