I bought a 1990 13' Scamp
last week and am doing a little work on it. I have a brand new dometic refer that I was giong to install in the Burro
I just sold. I took out the refer in the Scamp
and discovered that even though the proper vents were on the outside of the trailer there were large gaps under the sink cabinet that would let the exhaust gases come into the interior of the trailer up through the stove.
If I was not swapping refers I would never noticed this dangerous situation.
If you have a gas refer, especially if you have an older trailer, please check to see that the area at the back of the refer is completely sealed off from the interior of the trailer.
