Diesel vs Gas

There are good comments on this thread. We went with a pusher 4 years ago in large part because we are older and wanted a more pleasant drive -- quieter, smoother. Our 38' rig also drives a lot easier (more stable) than the gassers I tested. We don't measure mileage - I figure if we did that then perhaps RVing isn't for us. We have a pro do our maintenance - $350 for oil/filters each year. We did the tranny for $400 which is less frequent. We did our 90k service for $900 last spring. We use a mechanic that specializes in diesel trucks. I hope this helps and good luck.
