...'cuz with either one, you'll be covered, and you'll have tracking & proof-of-delivery. Obviously the NV215 is too heavy for the USPS, but that's pretty risky anyway, so I apologize for even bringing them up. A truck line may be a little cheaper than either FedEx or UPS... but, as 'Thor' suggests, packing that sucker up good is the key!
Good luck, and enjoy that cab! I've got one...
and an NV425...
