Furnace clicking noise.

When we first got our brand new 16’ Sport this spring we noticed a slight popping/clicking noise would happen every 1-2 minutes after our furnace shut off. Now, on our second trip, we can hear it every couple minutes while the furnace is running and when it has just shut off. It sounds like it is coming from either under the bed or out by the furnace and it’s loud enough to keep me up.

Any ideas before I tow it back to the dealership?

While an older trailer, my furnace does not have a filter on the air intake. If yours is like mine it may have sucked up something (construction debris?) and it could be hitting the blower fan. My furnace is under the galley sink. I can pull a trim panel inside the cabinet and see the furnace air intake. I don't know about yours.

Could be from the expansion and contraction of ductwork as the system heats up and cools.

^^ expansion and contraction^^
On the interior end of the furnace there is a metal box, the furnace plenum, that distributes the outgoing warm air. The plenum might be a manufactured part of the furnace or custom made and added during the build. When the furnace comes on the metal plenum heats up and expands differently than the furnace. The edges of the furnace and the plenum box are most likely connected mechanically by crimping and/or screwing, but there might be a few spot welds if the furnace was manufactured with the plenum box. There are also joints in the plenum box. The metal on both side of these joints move, so that slight movement of the two parts is possibly creating the sound you are hearing. The opposite happens as it cools, contraction, also creating the same sounds.
