That's great Sietze! Nice solution- I'd love to see how you did it- though I've nearly got it figured with regular lap belts (mine's not a panel truck). My boy was 2 in August, and I can't wait for that first ride with him. His first ride will most likely be my first ride too. I love that our boys will grow up with these trucks- I promised him a new coat of paint (if he wants it) by the time he's ready to drive it to prom.
