We have a 3911 Newmar Canyon Star and tow a Wrangler. This is the first gasser we have ever owned. We got out of 425 Cummins coach into this one and was disappointed in performance. But it is handicap accessible with a ramp lift. The more we travel in it, the better we like it. It certainly does not climb like the pusher, but it does get to the top. The V-10 does torque at a higher RPM but I don't like the noise that comes with it and (I know it is a mental thing) the tach at 4K.
Other than that, we are well satisfied with the engine performance and the coach itself.
