Great question, and this is one of those where I want to make sure you get the right cover the first time because they are not universal.

The first step is to identify the exact AC unit on the roof of the 2021 Highland Ridge Olympia Sport, since the shroud is matched to the AC model, not the trailer. If you take a quick look up top, you should see the brand name on the shroud, and ideally a model number sticker as well. Once we have that, I can match you with the exact replacement cover so you know it will fit properly, stay secure, and hold up without worrying about it coming loose or getting damaged.

Most trailers from that year typically came with either a Dometic or Coleman-Mach rooftop AC, but we’ll need to confirm which one you have before locking in the exact cover. These shrouds are model-specific and won’t interchange between brands or even different series within the same brand.

Here are some common replacement styles depending on what’s on your roof:

Replacement RV Air Conditioner Cover for Dometic Brisk Air II - White Part # DMC46FR (this one is very common)

Replacement RV Air Conditioner Cover for MaxxAir Units - Coleman-Mach / RVP Brand - White part # MA8335A5261 (second most common)

Replacement RV Air Conditioner Cover for Advent Air Units - White part # PXXMCOVER

If you can, check the brand name on the AC or send me a quick picture and I’ll lock in the exact one for you.
