In my humble opinion the only way to know how the coaches will handle is to drive them. The next best thing would be to get input from folks who own those exact coaches with the same floorplan. A lot has to do with weight distribution and over hang out behind the rear axle. And remember, almost every RV built will handle just fine below 40 MPH, although some will exhibit large side to side motion entering and exiting venues such as service stations. If you really want to know how it handles take it out on the interstate with the big trucks and even better pick a windy day. Having owned dually diesel trucks and large 5th wheels we had a rude awakening when we purchased our first motorhome. The second coach and our current coach also had handling issues when we purchased it, although not as sever as the first one. After quite a few dollars we now have this coach handling extremely well.
Most folks purchase RV's based on looks and floorplan, which is understandable since they plan to spend some time living in it. We had to learn the hard way that if you want to do any traveling and would like to drive for more than 2 hours without fatigue, then put handling at the top of the list.
