Hi bwagler,
Welcome to the Heartland Owners Forum.
A Mallard M260 has a GVWR of 6,900 lbs. By the time you add your gear, a few tools, clothing, kitchen stuff, and a little water and propane, you'll end up closer to the GVWR and to the empty weight.
So it would be more useful to get advice about your truck being able to tow 6,900 lbs.
I'm sure you'll get some answers shortly.
