Might be somethig you can do to get some improvement, although I am less qualified to advise in this area than many others. Our 30' class A does require constant attention to drive, and I usually drive 60-65 on interstates, and generally less onothers, depending on conditions. Although I do not like to, I have run as high as 70+, and it handles OK. However, at 80, I get REAL uncomfortable. Winds do have a big effect on it, always. As far as fear, if you are uncomfortable, then you might be too fast for conditions. Fear is not always a bad thing. Sometimes it helps you to stay out of trouble.
