We have a 2014 Thor Chateau 23U w/ Ford V-10. First drive was across the country, California to Missouri. The motor is a bit loud at higher RPMs and it will downshift on steep grades. The handling can be a bit disconcerting until you get used to shifting your focus farther down the road.
It's tempting to fix your eyes close to the coach to "micro" correct the small variances in direction. But when you feel more confident and move your focus 200 - 400 yards farther afield, then all of those small corrections disappear and the ride is very comfortable! My wife has been driving the coach without any difficulties for months!
We keep the rear camera on at all time and you can see when you are past another car or truck. We have the side mirrors set so we can see the side of the coach and the road lines with a quick glance.
Tire pressure and weighing the coach properly is important too, as is moving any heavy things: can goods, pots and pan down low and keeping lighter things in the upper storage areas.
All in all, this is a wonderful small coach and will go many places that a larger coach wont! Keep a tube of LockTite and a screw driver handy for minor repairs. Set it up how you like it and enjoy! Don't get caught up in the "have to fix this or that" and just drive it down the road!
