Re: 2008 Big Country 3490 bhs, has which rafters?
nalle09, Welcome to the Heartland Forum. It will be a guess for anyone to determine the rafter material. It would be best to get the VIN from the unit you are looking at and call Heartland Customer Service. They would be the best source. The reason for this is they made some changes back in 2007 and 2008 and it may have occurred mid production year.
