I guarantee that the Ford E-Series chassis will help you to become a more attentive driver. No knee-steering or hands off the wheel stuff. You will be blessed with a complete physical and mental workout which will keep you feeling younger the more you travel!
If you expect a class C to behave and handle like a modern car, or even a newer pickup truck - you should stop right now, sell it and either buy a diesel pusher with Liquid Spring option - or revert to car travel and staying in Airbnb lodging.
But seriously, the Ford E-Series is a commercial truck chassis. The components are primarily designed for load carrying strength - NOT passenger comfort. It will happily get you from point A to point B... just maybe not in the luxurious comfort as an oversprung Cadillac gunboat.
People with NO experience driving a class C generally start with a white-knuckle driving (me included)... until they learn to relax and "become one with the beast".
