My son, 3, loves trucks. Just loves them. Construction trucks, pickup trucks, delivery trucks, trailer trucks...doesn't matter. He likes the FedEx and UPS trucks, as well as all the different box trucks that you see on the highway carrying their respective loads.
Well, suffice it to say that when I gave him this almost 50-year old Lesney, it quickly became part of his regular rotation, missing rear door and all.
Beefy regular wheels on this guy.
Who needs a rear door when you have imagination!
