We went with a HR gas coach, used, and in great shape. I wanted a DP, but we are not going to travel enough to justify the extra initial cost and yearly maintenance of a diesel coach. The quiet and smoother ride will be missed, but since we are traveling short distances, the acceptable noise level of the Ford V10 is fine. I really don't hear it when the unit is parked at the campground...
For us, it was quality of the coach, affordability, overall cost and ease of maintenance. This coach won out in all those areas.
