See this link for the form.
I called FR direct and they filled out the form over the phone and took my credit card number.
Something similar to this is on the back of every Forest River brochure:
"For details on Rockwood’s complete warranty program, see your Rockwood dealer. When it comes to backing products with the same quality and commitment it has when it begins the manufacturing process, the only name you have to remember when you’re looking for a recreational vehicle is Rockwood. Rockwood offers the following additional limited warranties to the original purchasers. Consult written warranty for details.
1. Twelve-year vinyl roof warranty, 2. Two-year fiberglass warranty, 3. Five-year axle warranty, 4. Five-year tent warranty, 5. One-year
bumper to bumper warranty, 6. Available second-year warranty"
We did exhaustive research of numerous brands before our purchase and trolled this website once we decided on our Rockwood, so we knew about the warranty before we ever made a down payment. Our dealer did give us the form and told us about it, but then then again, he didn't try to sell us an over-priced after market warranty either.
