1. See your doctor. There are solutions.
2. Plan your trips so you can stop every hour or so.
3. Stopping to check your rig every hour wouldn't be that big of a deal. At 68 it's time to start enjoying the simple pleasures in life. Slow down a bit.
4. Do what the truckers do...just don't toss them onto the highway..:W
We travel no more than three hours on travel days. Stay off Interstates and use State Hwys. They are almost as nice, sometimes better and small towns litter the highway making frequent stops easier. You'll see more doing it this way as well. With over 80,000 miles on our coach, it's seen maybe 10k on the Interstate....Dennis
