So last trip a tire came off my trailer and did some damage as it went under the trailer. Today I started the repair of the fiberglass. I found a crack that went up and beside the vent of the furnace
. I took off the exterior cover, then went to remove the inside part of it. It would not come off. The interior pipe is some how attached to the furnace
it self. I went inside and took the cover off the furnace
and the drawer above it to get a look in behind. I can't find a screw or anything to suggest how to disconnect the two so I can pull the exterior part of the vent off so I can make the fiberglass repair. Youtube seems to be no help as all of the videos are for modern trailers. Hope someone can help!
