We've gone from gas to diesel to gas to diesel. Our last gasser was a 2003 Allegro Bay 37DB, Workhorse chassis. Can't say enough about Tiffin's parts and service departments.
I like the lower stress level of owning a gasser. Cheaper maintenance and cheaper to fix if something goes wrong.
What finally made us go back to diesel was the noise, the ride, and the drive. The noise wasn't bad in the cool weather but when it started warming up outside and the clutch fan stayed engaged most of the time the noise got really annoying.
No comparison in ride.
The drive is pretty close on four lane good highway but on the uneven two lane roads there is a night and day difference with the diesel being much more stable.
Just my experience with the rigs I've owned.
