How can I mount an LCD TV onto the *wall* of an RV?
Best bet - call the dealer or find the manual. Chopping up something like this is a risky proposition without documentation (manuals) or a knowledgeable tech because while you may find something with a stud finder you have no way of cutting into it and making sure you are not cutting into wiring/plumbing/vents/etc. Unless you want to pull the entire wall or rent an ir/magnetic camrea, you cannot do this with absolute certainty.
