We still have our suburban but now have an Excursion that we take on trips.
We built a 15 inch LCD tv out of an inexpensive $300 15 inch LCD computer monitor and an $80 RCA to VGA analog converter. And a $60 stand for rolling mill from Harbor Freight Tools.
Again we used a 400 watt invertor to provide ac power to the tv and to a SONY DVD player ($120 at
WalMart - must have the spindle that you snap the DVD onto).
Mounted the LCD screen onto the adjustable stand, bolted the stand with three 1/4 inch bolts to the floor between the front seats. This stand has the ability to raise the tv as high as the ceiling for passengers in the third seat and also allows for the tv to be swiveled and tilted.
The stand was originally designed to support steel stock of up to 2000 pounds in weight - so I feel it won't go anywhere in a car crash.
This was a major improvement the 13 inch screen tv because we can now reach around it to the back seat, it's thin - takes up less room(about 3 inches thick), uses far less power, does not obstruct the view (we keep it all the way down usually), has better viewing.
We keep the DVD player, remote, etc in the console between the front seats - if your child is older give it to them.
