I continue to be amazed at how people are so sensitive to speed and others getting in their way!! If 60 mph in an RV (that's a mile per minute) is not fast enough maybe you should consider another mode of transportation. Driving in other types of vehicles is a different consideration and speeds can increase in a prudent manner. Any type of RV both those you drive or tow should travel somewhat slower or as close as possible to the posted speed. The vast majority of drivers today want to travel 10 to 15 mph over the posted speed.
