So, I'm on the road on a business trip, and #1 son calls and says that the Rhino died (That's a 2001 Monty Ltd).

I think I need a new motor (3.5 litre V6)

1. Where can I buy a motor?
2. What is a fair price?
3. Should I rebuild instead of replace?
4. What is the significance of "R" as the 8th digit in the VIN (An ebay listing calls this out)?

Thanks in advance.
