Stuck Suburban Furnace

[S. Lowe]

I had to remove the Suburban Furnace from my13 ft 1981 Scamp to clean out dirt dauber nests. Now I can't get it back in. It pushes in all but about the last inch and then it sticks. It must be the inlet or exhaust tubes, as I can't see anything else to hold it up. Any suggestions or previous experience out there to help me out?

Try shining a bright light in the grate from the outside of the trailer while someone wiggle the furnace from the inside.

You might see some kind of misalignment.

Then, maybe you can get some kind of metal or wooden rod poked through the grill to get things aligned.
