A/C Shroud Replacement Needed '97 Scamp

[AJB]

I've got a '97 16 foot Scamp with a Coleman 6727 mini mach roof top A/C. I need to replace the shroud and was interested in the one by Maxxair. Doesn't look like it fits though. Who else has this A/C and have you replaced your shroud yet?

Thanks.

Maybe before you plunk down $100s or so why not take $1 worth of fiberglass resin and mat and try to fix it? They do crack easily, so will the next one. Maybe you could just put some duct tape on the outside over the fissures or cracks, then fiberglass/resin/hardener/glass the inside, bolstering up the structure, where it doesn't show, then when set, take off the duct tape and put a bit more resin/hardener on the outside to secure it all. Spray paint it with plastic white Rustoleum. Like new? Wear a respirator and gloves, the fiberglass shards can eat their way through your skin. Other than that it's easy enough.
~OR~
Use a plastic welder, which is like a saudering iron for plastic, and some plastic sticks which usually come with it. I once got a $500 2 man canoe for $50 because it had a hole which I fixed with a plastic welder, and is water tight. It's a bit blobby looking but effective, so you may want to try this on the inside too.

Adam, you really didn't say what's wrong with the AC cover. Just cracked, pieces missing or whatever. If it is just cracked a bit I agree with the suggestion to repair it from the inside. Just want to give you a little heads up. AC shells are not FG but a plastic. Using resin may just cause it to "melt" down from chemical reaction. Don't ask how I know and it wasn't the AC cover. Lets just say that some plastic pieces on RVs, PVC pipe for reinforcement and PVC glue aren't a happy mix....nor cheap .
I'm sure someone here with a lot of FG expirience can tell us if that is a good idea.

Thanks for the fixing suggestions boys but this ones far too gone. The Florida sun has made this into paper. Even the slightest push with a finger turns it to dust. So buying new will be money well spent.

I feel your pain Adam, I live in the desert and the sun does a job on everything. Just a thought though, when you replace it you may want to get/make up a cover for it to block the UV. Kind of like what you can get for covering a swamp fan for the off season.

Yep. Actually bought a cover and built a cover so she's double covered.

when I got my 98 casita, the AC cover was pretty bad. When I pulled the cover, I found that the fan blades were just as bad and crumbled when touched, You may want to check them too. I took mine off but in the south that wouldn't work! This time of year the last thing we have to worry about in Edmonton is UV damage from the sun as its so low on the horizon. Hey but we are suppose to hit about 40F today, sure beat-40f!

The Mini-Mach is no longer in production, but I have some good news!
I was in Shipshewana In. recently with a friend who was getting his motorhome A/C repaired. The place had a couple of mini mach shrouds in stock.(used in excellent shape.)
I asked them because I have a mini-mach.

These are very nice and reasonable people to deal with.

When replacing an A/C shroud, I think it is wise to replace the large fender washers on top with a strip of aluminum on each side running the length of the shroud. Too many shrouds have been left along the highway due to cracking around the washers.
For your Florida application... Why not install a piece of white Rollex sheet metal (soffit material) to cover the entire top (just the top) of the shroud for sun protection?Then just place the aforementioned aluminum strips over that.
