The body is more plastic than diecast, thus it's very light and anything heavy in the bucket tends to tip the caterpillar. I will add some weight to the back end, as I want it to display moving 1/64 cars in a junkyard. The fork is diecast and sturdy. Getting the fork/bucket to move up and down is a little tricky as the mechanisms are plastic and you want to extra careful so nothing breaks. Once it's moved it becomes easier. Overall it meets my needs and it looks size appropriate for 1/64.
