Often as not, this comment comes from a woman, yet lots of women own and drive their own trucks or RVs. Some day, you may have to. I just could handle the rig by myself. She managed to get back to civilization, get George to the hospital, and take the rig to a nearby RV park. George got better, but now they share the time spent behind the wheel, for it was determined that sheer physical exhaustion was the major contributing cause of his illness.
Nobody ever expects things like that to happen, but happen they do, and it's best to be prepared.
There are several ways to do this, such as driving schools, videotapes, books, experienced RVers who will teach you, or perhaps the dealer where you bought your rig. Just don't get discouraged. That's why they pay people to do it. Soon, you will become familiar with the various techniques and begin to develop real skills. After a while, you may want to take the rig out on the highway for some practice with the mirrors and signals while changing lanes, shifting gears while climbing hills, and using the gears and brakes for coming back down.
