Since I bought it used, I'm not sure if my transmission is shifting into 6th gear.

What RPM's does your engine reach going 60 MPH?
I'm at about 2,100 RPM.

At 60 mph, on flat road, mine is in 6th gear at about 2000 rpm. Downshift to 5th usually occurs when hit a slight incline. Kicks up to about 2300 rpm. What makes you think it’s not getting into 6th gear? You have a longer wheelbase, heavier coach. I would think yours has different rear ended gearing than mine.
