This article from Popular Science compared two very different motorhomes from the past considered to handle very well, almost car like.
August 1973 Popular Science Review
Although one was a Front Wheel Drive GMC and the other a "gasoline pusher" manufactured by FMC, they both shared a low and wide aero design (at least aerodynamic for their time).
Specs for the FMC motorhome include a height of 8'-8", and the Classic GMC was about 9-feet to top of AC.
And it may be hard to believe, but they both had independent front and rear suspensions, which just shows that motorhomes can be designed to handle much better if it is a priority.
Most of us know what Classic GMCs look like, but in case you are not familiar with the FMC gas pusher.
