New Cougar - Furnace wont heat above 60
Just took delivery of a brand new Cougar 33SAB travel trailer. For some reason the furnace will not heat the inside of the unit to more than about 58-60 degrees... its been about 25 degrees overnigh...

Also, it seems as though every few minutes it'll blow cooler air for a while and then go back to somewhat warmer.
My main duct in the floor was collapsed as built new. Did my best to prop it open but the solution was to add two more ducts. I assume yours is different but similar issue.
