Without examining the configuration in person, it is difficult to judge the possibilities even with a photo. It may be the mirror has to come off, the Corian top removed, or there's well-hidden exterior-accessed screws yet to locate. My guess is that there's brackets inside, screwed into the front frame, that trap the TV in place, and the best real access is by removing the mirror. Obviously that requires someone that knows precisely how it's mounted and what they're doing - I don't see mirror clips, so glue must be involved. I'd probably get exasperated trying to deal with that and just resort to a hammer, coughing up the expense of a new mirror
. Just kidding (I think
).
Our rear TV cabinet had wood buttons in front hiding long screws as I recall. Jim Sizemore at RV Outfitters knows these coaches, and could probably get that TV out in nothing flat. It doesn't look like you have much wood trim left up front as it is, but he may be able to put an even larger set in there by having his co-counsel, Greg Fulton, make new trim like they did for us, back and front TV's. But the size you have now may be just fine; upon reflection and some admittedly minimal rear TV use since the conversion, the unit seems a bit too big for its distance from the headboard of the bed. They are both ex Beaver factory fellows; I dunno about '06, but I think they were both at the original Bend factory, much before Monaco built yours and ours. Greg was and is by many considered the premier coach woodworker in the country. Only Junction City's old Country Coach cabinet makers could come close in my opinion.
Additionally, Beaver Coach Service across the street has a very talented young woodworker, among others, who could do the job. Their reputation for maintaining the Quality Beaver cabinetry is unscathed, as many here can attest.
