This is a very intersting and worthwhile discussion. We all have different priorities when it comes to entertainment when camping.
Personally, I wouldn't bother with broadcast, cable, or sattelite TV. However, a portable DVD player might be a good way to pass the time on a rainy night. I love music, especially blues. Also, I like to get some news and a weather report in the mornings, especially when we're trying to decide between sightseeing in town, spending the day on the beach, or paddling on a nearby river.
I avoided built in entertainment electronics when planning my build. I prefer portable devices that I can easily move around. In campgounds, one needs to be considerate of the neighbors. I can keep portable electronics very close to me. This allows me to keep the volume levels at an absolute minimum.
Just prior to our maiden voyage last year, I picked up an XM Roady 2 reciever. I really love XM. I hardly ever listen to AM or FM any more. We used it in the car on the long drive to Florida. We also used it the galley of the TD. I played it through an el-cheapo boombox from Wally World. It was a pain moving it the antenna and power adaptor between the car and the TD. Also, we had wires running all over our galley.
This year, I plan to updgrade my XM radio to the SkyFi2. I am also going to get this boom box unit to go with it.
This thing runs on AC, 12V DC (w adapter) and D-cell batteries. This way , all I have to do is move the radio. In addition to XM, it plays CD, MP3s on CD, FM and AM radio. It also comes with it's own XM antenna with a 10-foot cord that you can either leave on the back of the unit, or detatch for better reception.
I was in Sam's club last weekend and spotted a special bundle, with the SkyFi radio and this boombox for $145. That's a GREAT deal. I plan go back there on my next payday. If they still have it in stock, I'll pick it up.
