Lowering the seats my help but the truth is big guys have troble getting in and out of this car period. I'm 6' 1" and have issues, in a Limited with power seats.
You could also do these things;
Take off the Stetson
Lower the top
Go to the gym more
Take two Aleve before trying to enter.
Move the steering wheel fully forward
Move the steering wheel fully back.
I have tried all but the Gym thing. With limited results.
A few bourbons or a scotch will help you get in but is generaly not recommended if you intend to drive the Crossie somewhere.
Or dothe Schwartzenager thing and pull the seat fully out of the car and sit on the floor. But then you couldn't lay your arm on the window sill.
