What other Heartland series is the MALLARD based on?

Trying to locate more information on the Mallard in general (ideas, troubleshooting etc).
I understand the Mallard series is a Camping World exclusive series, and I would believe it is based on one or more existing Heartland series with many, many commonalities.
Who can shed light on this?
Thanks.

North Trail is it's sister trail. Built on same line, etc.

Perfect. TY.

You will notice the similarities. Ie: M32 vs NT 32BUDS, M33 vs NT 33BUDS. With the NT you have options available to customize at the factory that you don't with the Mallard.

Call Heartland if you have specific questions. They are really helpful.
