I had a 2011 Coachman Class A on the Ford F53 chasis equiped with the Ford V10 - 362 HP and sold it to purchase my 2012 Forest River Berkshire Diesel on a Freightliner chassis and powered by the Cummins 340-HP.
I can tell you that the answer is definatly, YES!
Last year about this time of year we were heading north from Bradenton FL and had cross winds in the 18 MPH range with gusts of 30+ MPH. The wind blew the coach all over the road. Body roll plus moved the coach a foot or so to the right when the gusts hit. Yesterday leaving Bradenton, FL we had cross winds of 23 MPH and gusts at 40 MPH + and while the cross winds did bump and bang on the side of the coach it didn't push us around much. The extra 7,000+ pounds, plus the air ride really helped keep the coach planted on the road.
If your considering a DP, there are many more advantages than just the ride, but they come at a steeper cost than gas.
There is no right or wrong way to go. Gas or DP both have advantages. Buy what works for you.
