Replacement Shroud for Coleman TSR Mach 3 Unit

Updated 05/31/2025 | Published 05/13/2024

Question:

Our top cover is broken on this old TSR and wondering if this would fit? I would like to see any mounting instructions as will it encompass the whole unit down to the roof? Thank you.

Hey Andy, yes the Replacement RV Air Conditioner Shroud part # MA00-325001 that you referenced is correct for your TSR Mach 3 RV AC unit.

Basically you will need to remove the hardware on top of the AC unit shroud to remove the old one and then install the new shroud with the included hardware.

Hey James! Do you have any idea how to figure out which shroud to get if: the original shroud is gone, the model/serial number is rubbed off the data plate on the exterior piece, the data list with serial numbers of installed appliances says n/a? The internals of the unit measure 22.5 x 32.5 x 12 3/4”/. So I’m not sure how much larger the shroud needs to be than the internal components. It’s a 1998 Coleman bayside by fleetwood. The A/C control unit only gives me the logo “Coleman tsr (which is OEM and don’t know which Mach version it is). I have looked at a lot of different ones, just not sure what is right. I have found a few with the correct mounting hole measurements and placements, just don’t know what to get. Any and all help is greatly appreciated!!

@Kyle I wish I could attach pictures to this page but check out this answer page that Bryce made and on it you'll see one of the Coleman AC unit shrouds we have and all it's dimensions that I think might work for you. https://www.etrailer.com/question-803483.html
