I completely agree with this.
A couple of years ago I was parked at the Freightliner Service Center in Gaffney, SC. They have about 22 spots for motor homes, all with 50-amp electric. Most of them are back-in sites.
I was parked in spot 7, and there was a coach to my left In spot 8. Spots 9, 10, and 11 were empty. A 40’ coach pulled in and attempted to back into one of the three open spots. On his first attempt, I was about to dive for my door to get outside and stop him because he was going to hit the coach to my left. Fortunately he realized this in time and stopped. He made two more attempts to back in, and both failed miserably. He wasn’t even close to being properly positioned to back in to one of the three open spots! And he drives this coach on the highway? Yikes! He finally gave up and parked in one of the pull-through sites, even though he didn’t have a towed.
I think there should be a National driving test and a special RV license required to drive these big vehicles.
I also think your neighbor, with the bus driving experience he has, will do just fine in his new coach.
