Throughout the years there has been difference AC heights and difference hights do to lift kits and wheel heights. Even within the same year you will find these variances.

I would check the TM web site for the specs for a good starting point. But the AC height is most likely shorter compared to older models. The rooftop height is a little higher on the current model than older models. But some people have added lift kits and taller tires on older models. I would bring a tap measure and 4 foot level if the measurements are close to you garage door height to get actual measurements.
