The wife gave the go ahead for a pair. It hurts watching the boys sleep in the booster seats on the trail. Their little heads just bobbing around. I will probably go with the strapping to the seat, so we can move them between the trooper RS and the VX. Maybe I can fab a frame for the VX. We have decided that she is going to daily drive the RS, and we are selling the 2010 F150 and getting a 2004-2005 F250 diesel and a goose neck dual car hauler. I know its off topic, but it relates to the car seat, which in turn relates to folding up the rear seat
