I have a 2001 Coachmen Catalina Sport, the unit is under the rear dinnete bench, on the righng the side. the braker box, and fuse panell are under the pantry, on the left side,brown metal cover, if you have a rear bed, look under there, they also hide them, under the couches.
Thanks for the assist. I did find the converter under the kitchen cabinets hidden behind a cluster of duct work. The vents and fan looked pretty clean so I just vacumned the construction trash that was left in the area and closed everything back up. It sure looks expensive and very very difficult to change out. They definitely weren't thinking about ease of maintenance when they designed this layout. But at least I know where its located now. Thanks again!
