Any tour of a manufacturing facility is worth the effort - says the 35 year veteran manufacturing rat.
You won't see every plant, just one of several near the welcome center. We went in March and luckily toured the Pinnacle / Eagle Premier 5th wheel plant - good for us. If your into reading some if the history about a Jayco, the welcome center is worthwhile. The video before the tour tell a neat story about the family.
A drive around the area seeing just how many RV's are produced is eye opening. A meal at Essenhaus is pretty good.
With a 13 hour drive, I'd make it a side trip to a camping vacation. Maybe a few days of winery tours on the eastern coastline of Lake Michigan or an amusement park like Cedar Point in Sandusky, OH?
