We just went into our second gas coach. Number one was floor plan. We got every feature we wanted. I was very familiar and comfortable with the F53 chassis, handling and upgrades to improve that. After about 20k miles on that first gas coach I was very comfortable in the driver's seat. Not impressed with the cost of a diesel and the maintenance that goes with it and the, generally, more complex systems they incorporate, we went for a high end gas coach. I am a DIYr for maintenance and felt the diesel coach and it's systems would be beyond my mechanical abilities, or at least my desire to do that maintenance.
