Since you seem confident and comfortable with driving a larger vehicle including your MH I'm not seeing the source of your fear. The difference between 50 mph and 60 doesn't seem to be that big. I have a 30 ft. MH and my fear is the fact that one cannot back up towing flat but it's a manageable fear. Actually I never drive over 58 mph so maybe it would help you to just not try to go 60. Even 55 is OK and legal.My son is stressed driving his 35 footer and plans to downsize. Some fear is normal and healthy. After all these darn things don't handle well or stop fast.
