I've got a little input for you from the other side of the equation, the customer / driveway service side.
I had to make arrangements last year for a family friend to get their Motorhome back north after the DH passed in Florida over the winter.
In order to preserve their reuptation every driveway service has a few basic rules for drivers, basically, NO smoking, NO pets, NO possessions other than minimal luggage, steady, productive driving, no sight-seeing (mileage is checked) or dawdling, 8 to 10 hours of highway driving per day, only weather or break-downs excepted. In the case of RV's, most require that you NOT sleep or cook in the RV.
One drive-away service rep told me flat-out, they'd list the trip if I wanted, but in 10 years he'd never yet had anyone willing to drive one based on their requirements.
