Lots of good thoughts here. If all works out the way we want it to, we'll be 63 when we purchase our first DP. That will be my first experience with anything diesel, so there will be a learning curve there. I've driven an old school bus (manual transmission), and a MH has to be easier!
That said, I will want the seller to drive the coach to a parking lot so I can practice a bit under his watchful eye. I'll tell him that if he feels uncomfortable with my driving at any point he is to immediately speak up. I'll park the coach and let him take it back. He won't make a sale, but we will have some serious discussions about the wisdom of buying a DP. It may be that I'll try to get more instruction and try again, or we may decide on something else.
Looking ahead, at some point we will need to sell our coach. I'd hate to sell it to someone who promptly goes out and kills himself or someone else because he wasn't at all qualified to drive the coach.
