We have a recently purchased 2004 Pleasure-Way. Supposedly, everything worked. But the TV doesn't. Since it's a 2004 I'm thinking it may not be able to receive digital cable TV. If that's the case...
I agree you will need a converter. But LCD HD TVs are really inexpensive now. And much lighter than those old TVs. If your mounting arrangement (and skills) allow it I would buy a new TV.
