Question:
Our 1995 American Star trailer is 30 feet long. Would the DMC64MR be oversized, or is that the right size furnace for a rig this length?

Expert Reply:
Joe, for a 30-foot trailer you’re right in the sweet spot for a 35- 40k BTU unit like the # DMC64MR. It’ll give you even coverage across your ducts without struggling in cold weather. If your trailer is well-insulated, you could technically get by with a 30k BTU, but I would just stick with 35K.
Does your grandmother’s rig still have the original ductwork intact?
Also does your 95 travel trailer have a service door for sure? If so, the # DMC64MR will work, but if not, you'll instead want to go with the # DMC74MR so you don't have to cut the RV wall for the door.
