Looking to replace my side vents with fancy new plastic ones. Having a hard time finding my rough opening sizes so I don't have to make any cuts.

The fridge vent rough opening is 20" x 12"
The LPG vent rough opening is 13.5" x 13.5"

Has anybody done this? Would you point me in the right direction please?

Thanks Everybody.

I can't speak to the LPG vent, but my coach does have one of the nice looking plastic vents on the side for the refrigerator. It was installed by the P.O. and it appears he had to cut the opening larger for it to fit. It has not caused any problems. I guess you could buy a vent cover and spend a bunch of time cutting it down to fit, but It might not be worth the effort.

Try contacting Jim Bounds at the GMC Co-op in Orlando. I remember reading something on his blog about installing those refrigerator vents and some special modification he does to them to make them conform to the body curve better. He can probably supply the vent AND provide instruction on how to best install it.
