Totally agree....it's all supposed to be about a simpler life.
Our fusion stereo with inside / outside speakers has only been used once ...to see if it works ok.
Radio....we carry a good Sony transistor which is easy to move, control and can't possibly intrude on anyone else. We've been subjected to others music too often in the past.
Music ....MP3 / iPod dock for same reason as above and we use earphones most of the time
Tv antenna...snowdrop thingy which works fine for our limited needs, certainly far better than the homemade makeshift one we had on previous vans. I laugh now when I think of it but there were very few available at a reasonable price when we decided to make it up from useless stuff we had in the shed.
Geez....we sound boring...but we do read a lot!
Fusion package, as I said, was an inclusion we didn't ask for but kept to give us better resale value. We seriously thought about asking them to remove it.
It's all about what you want from the camping experience...for us, it's peace, tranquility, a different place to explore, relative comfort and relative safety.
Ah, as someone said, the serenity!
Will let you know how I get on. I am half tempted to forget the whole caravaning thing and book a 5 star resort holiday instead
