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 have a 2007 Excel with the 19 in. flat screen TV with analog tuner. I inserted a A/D converter downstream of the antenna amplifier and if works well. It is just another small piece of equipment to secure and connect but for the amount of TV we watch it does the job. We usually camp in places where there is no TV signal whatsoever. The only problem is that such converters may be hard to find these days. Beware of repackaged ones that look new but could be defective.
