Not a Mallard owner, but welcome to the forum! I understand the Mallard is a Heartland product built exclusively for Camping World. We've seen a few new owners here this year, but not many. And I haven't seen anyone report any issues here.
One thing I'll say is that Camping World does not have the best reputation for service after the sale. Not to steer you away, but to make you aware. Heartland does allow other dealers and independent repair facilities to work on your trailer, with prior approval, so know that you don't have to go exclusively back to CW if you have issues.
