What would be nice is that the RA provider provide the customer a vehicle page where can log in and complete information on your vehicles and update it as you wish. I can tell them what tires are on it, I can GPS where I am at (as if I didn't already know), but answering the questions before hand and having that info on file would be a great help. Having a blow out on the side of a freeway during busy traffic is enough of a stressor, but then having to try to provide all if this info to the CSR, AND having SWMBO yelling into your ear and having an attitude would spell disaster, plus if she had an issue with her car there are questions she couldn't answer, and heaven forbid she be driving my truck and have to call. I know with a near infinity of options and combinations, the form could be mostly a "notes" field where the owner can put in as much as they want to. Adding that you have a Lippert full wall slide or auto-leveling system that would help if that was the issue and they could relay that to the service provider so they may find out if they are familiar with that particular system.
