Paul and Shelley, We always like to hear the feedback (good or bad). All units are wiped down thoroughly in the last step of the manufacturing process, but here is the deal. There is still dust in the vents and, I am sure, other nooks and crannys which causes shakedown. Ultimately, while the unit moves down the road, after production, there is always the opportunity for dust to get back on the counters, appliances, etc. This has been true for all 4 manufacturers I have worked for.
In regard to the mounting bracket, it is based on the bolt pattern on the back of the TV. We have no problem selling you an additional mounting bracket for your unit through our parts department, but there is no guarantee that it will work with your extra TV. Just talk to your local dealer and tell them to order you another bracket. If your TV has the same bolt pattern as our TV (100mm x 100mm) then we should be able to get you the bracket. If not, there is a chance that our additional swing arm we provide in the outside kitchen may not work with the bracket you go with. In that case, you would have to replace the swing arm as well.
