Thank you. Makes sense, but a 42 HP drop sure looks bad even if there is not a noticeable change.
I have the almost same Ford V10 in my Class C, at 305 HP, and have concerns about trying to climb a hill in a much heavier Class A with just 15 more HP (320 HP).
I don't know about the 5 vs 6 speed change, but will be looking for the stats.
Thanks.
