Refrigerator Vent Modification? Anyone?

Sooo. My new fridge is shorter than the old one by about 5 inches or so. Has anyone ever tried to extend the existing plastic refrigerator vent? If so, what did you use? I have thought about raising the shorter fridge on a platform, but then the access door might be in the wrong place. What do all of you experts out here on the Argosy forum think?

I would think raising it would be the most cost effective, just make sure that if your model has the venting hole cut in your floor it is not blocked off. The floor venting is necessary for the chimney effect for the proper operation of the fridge. Some years and models have venting in the access panel :-)

Otherwise you could rivet a plastic patch on the lower part of the shroud. Go to your nearest plastics place / signshop and see what they have on hand that will bend enough to make the curve needed

You have a problem only if you removed the counter top. The cabinet, floor, and counter top form a box that holds the fridge and contains the air flow past the coils in the fridge and keeps the exhaust from getting into the interior of the trailer. The exhaust then flows up the scoop and out the top vent.
You could raise the fridge a little on a platform, then trim out the front of the cabinet so the flanges on the front of the fridge seal to the cabinet. As long as the fridge burner is sealed off from the interior of the coach and the fresh air inlet - exhaust outlet path is clear, you should be OK.
Two asides:
1) That scoop for the fridge exhaust is likely to be fragile after 39 years. They break and they are expensive to replace. Inland RV has replacements but you will likely have to mess with it to get a good fit. Or you can build one yourself.
2) Did you use the Dometic replacement sheet to pick the best fit for the new fridge? They don't fit exactly but it is close enough to minimize the amount of fitting you have to do. 5 inches sounds like a lot of difference to me. When I replaced the fridge in the Minuet, I used a RM2351 as the replacement and had to trim up the bottom and side to get it to seal.

If you go to Lowes, they carry a sheet of fiberglass that is 8 square feet for about $7.00. You can also get a gallon of fiberglass resin for $35. I personally would pull the old scoop out as carefully as possible, then lay the fiberglass cloth on the inside of the old scoop to reinforce it, and then exend it down. Personally, if I were to do it, I'd get blocks of styrofoam and then carve it out with serrated knife and then rough sand paper. Then, find a box of Reynolds easy release foil. Spray the styrofoam with spray adhesive, then put the non release side on the foam. Now you have a form. Put that on the end of the fridge scoop, then lay fiberglass the full area you want to cover. Glass the whole thing, and trim the edges later. Finally, flip it over, use bondo to smooth the connection and you should be golden (if you want to go through the trouble to make it look like it's supposed to be there.
