searching for a coach

Well the learning curve continues , I drove my first class A's today and learned a little bit but now have more questions. First coach was a 35 foot bounder on the ford chassis and I knew from my last post to expect noise and high rpm - all the shifts seem to come at around 3k rpm which I guess is normal for the v10 but will take some getting used to after my diesel truck. Handling took a little getting used to seemed to wander a lot which I guess is also normal I know they are not sports cars but thought they would handle a little better. Second two coaches were Itasca Solei's 36g's love the floor plan but question the quality because the first one had the check engine light come on and could barley make it up and entrance ramp to the highway the second one sounded like it had a suspension issue making noise above and beyond what I guess are normal rattles and other noises in a motorhome on the road. The Solei's seemed to me to be a bit underpowered with 340 hp and the handling at highway speeds seemed lose and not at all what I would have expected for a pusher. So two questions is this enough engine for a pusher of this weight and do all motorhome handle , I will use the word lose? The good news is the trade in value for my current equipment. The dealer which offered the same trade in value on anything I bought from the Solei's Down to a vista and he was about where I thought the numbers would be. The second dealer was lower but says the deal was in the discount ,don't like this guy . Not sure why the first is giving the same amount for any of the coaches I looked at and his prices were discounted a bit from listed price? The search goes on . I like the pusher but not the power or handling of that particular chassis. Thanks for any input or help ,you guys were great with dinghy towing questions thanks again
