Hi Craig,
As a suggestion, if the Dealership won't give you the previous owners contact info, you could ask the Dealership to contact the previous owner on your behalf and give them "your" contact info.
The previous owner can then decide if they are interested in communicating with you.
If the Dealership refuses to do that, it would make me think either they have something to hide, or they really don't care about any future business from you!
I'm not sure if Fleetwood would, or are allowed to give out this info, but it never hurts to ask.
One more thought, do you have a system in the US to get a vehicle's history through a Government department?
In Canada, we do have a resource for this, and as expected, at a cost.
Good luck.
