We use netflix streaming where there is adequate bandwidth. DVD's for the rest.
Last spring I replaced the 100lb Magnavox tube TV with a 32" Panasonic flat screen. The sound wasn't up to snuff....so installed a 300 watt sound bar along with a 100 watt powered sub woofer. Now we have basically a "home theater" on the road. We love it.
This isn't "camping", this is "glamping". Call it what you want....I used to walk into the woods with a Bowie knife and come back three days later, eating what I could kill with the knife and inner bark of a pine tree (tastes like spearmint, actually...) The Silver Tube with a kitchen, a bed, and home theatre is better
