Newmar Warranty
How does Newmar Warranty Policy Work?
Answer: All of the power products which Newmar manufacturers are backed-up by a two year warranty, parts and labor, from the time they are first purchased by the product user.
On products that are past the two year warranty period that need to be returned to the factory for repair then qualify for a one year warranty.
All repaired units are tested at full loads and all circuits are carefully evaluated. Parts are upgraded if necessary, even those which have nothing to do with the reason for the repair, before it is returned to the customer.
Newmar Serial Numbers
How to read a Newmar Serial Number?
Answer: Knowing how to read our serial numbers makes it easy to identify the date of manufacture. The number is set up this way: First two digits represent the year, second two digits the week, and the final three digits represent the unique sequence number. For example, a unit with a serial number of 1327838 is the 838th unit manufactured in the 27th week of 2013. Please note that this protocol was established in 2000, so this code does not apply to units manufactured prior to this date.
