I have a 2001 Georgie Boy Suite on a Workhorse chassis that I bought new. About 7 years age it would not crank right after I made a stop on the road. They had to replace the ignition switch that is ...
Things where you stick the ignition key in the side of the steering column do now ever have the actual switch there. The key moves a rod up and down the column, and the actual switch is bolted to the side of the column under the dash somewhere.
/there are adjustments in the steering column that effect the movement of this rod.
It sounds like yours has never really moved far enough.
