We took the factory tour last year while attending the FROG rally. I thought the tour was very interesting, informative, and well worth the time. The rally attendees stayed at the Elkhart County Fairgrounds.
There will be another rally this year in early August and you might consider attending. It's a great bargain and offers a chance to meet many other Forest River Owners. You can find more information about future rallies and events in the subforum titled, The Rally Zone | F.R.O.G. Events. You can also find information at the Forest River Owners Group website at FROG - Forest River Owners Group
