One of the main reasons we decided to sell our Class A was the fact that it was physically impossible for DW to drive it because of her height.
The F53 chassis has no telescopic steering column adjustment and limited angular adjustment. The Flexsteel seats had no height adjustment and not enough fore/aft. Her feet didn't reach the floor and she had a foot-stool on her side of the cab.
Unfortunately, we didn't check this stuff out when we bought the rig. When we realised the predicament, our emergency "get you home" was a one-way airline ticket for our retired son-in-law or another family member to come for us.
