DW and I have different opinions on this sort of subject. I don't feel comfortable letting the kids roam around free in the cabin in case of an accident. I like them strapped in the seats. She then reminded me of how I grew up riding on the back of my dad's pickup. She also reminds me that part of the reason we went from a TT to a Class A is so that the kids could travel comfortably. To me, it just doesn't make sense that the two adults up front wear a seatbelts, but the kids outback don't. On our trip to FL I would fire up the gen to let our older one go into his bunkbed and watch a movie for a while. The way I figure is that when we used to make that 1k mile trip on our truck w/TT they would be in kiddie seats the entire time...at least on the coach they can take breaks and get up, go to loo, etc.
We got our oldest one an Ipad to keep him busy this coming up season and I'm going to run an extension from the inverter to either the kitchen or dining area. He can keep his Ipad charged and one of those portable DVD players should be good enough.
Your idea sounds good...a little complicated, but could be done. I'm sure there are different thoughts about the seatbelts. DW and I will still be talking about it next season.
