Have RV Questions? Ask an RV Mechanic Online.
The best way to tell what that is would be to Google for a brochure on that year, make and model. Most will come up and look at the specs and most show the size and type of tv. Another way would be to Google that year, make and model and find one for sale and call on it and among other questions, ask what size the tv is. I have found this sort of information more than once for customers this way. Hope that proves helpful.
Just checking back in to see if perhaps you missed my earlier response to your question or if not, do you still need some additional input from me here?
