took my son in the truck for the 1st time. he turned two, two weeks ago. and it was GREAT! he had so much fun, loved sitting in the front, up high looking down at all the cars, and he really likes all the noises.
I still have no seat belts, but got a bench seat to replace the original bucket seats. then bolted three D-rings in the bed (easy with the panel truck) and strapped his car seat to that. his seat should be at least as safe as a regular car, and any car that gets in our way gets eaten anyway.
