Slightly off topic but if you want the TV for the kids while you travel I found that either a cheap portable 8" DVD player or for older children I use my laptop to play DVD's. Since you already have the inverter you can plug either in to charge with a much smaller drain on your house or chassis battery. Walmart $5 bin and Redbox and most Walmarts can be your friend.
I always worried about that TV being unlatched while moving. Mine is set up such that if I would accel to fast the screen would meet the corner of an overhead cabinet.
