Here's one
link for 2013 vehicles, I gave you last week on one of your other threads about towing. As I stated last time a vehicle that is rated as towable from one model year might not be towable in a different model year, or the procedure/requirements might be different.
I thought you intended to try a few trips without a toad ?
I had a 22' class C and currently have a 24'er and a 32 1/2'er. I never had the need for a toad with the 22' or the 24'. I've had the bigger one since last March and in about 13 or 14 trips I've managed to get by without having to tow anything.
