This is exactly why I believe there needs to be a special certification on your driver license for towing anything above an 8 foot utility trailer or driving any kind of RV. It should be a national requirement much the same as being over 21 to drink, or the state loses road funding from the Nat'l Gov't.
In Florida... you have to have a special certification to drive a motorcycle, but not a 45' Class A motorhome. It really scares me to see an 85 year old person who has compromised reaction time, and that can barely walk, driving a huge motorhome. (or even a car for that matter).
