It appears to be the new normal.
You can still get service, you just have to wait. What do you expect? Tons of people buying RV's, and some actually taking care of it.
Tip: Check with Ford Fleet Services, I found one, thus 1 hour away, which works on Ford Motorhomes.
An of course, now with the season starting, everybody is booked out for weeks, months. We get our spring/fall service done in around February and November each year, never had to wait for an appointment longer than a week or so.
