Wow that is mint. Mine is called Big Mike, it is similar but has a long nose cab and 2 rams to lift the deck, it is red/orange in colour, but no where near that condition, I heard "Tonka Tough" and took them at their work, It was well loved, and definitely not neglected. I'll try post a picture, he is still a favourite in our house when there are boys around.
I guess I am not a collector, as mine are old well beaten toys, so that must make me a Horder
The other one I have is a VW Beetle called Twinkle Toes. The Boxes are long gone, probably ripped in the rush to get to the toy.
I will add Photos soon, but you will see they have been well 'Loved'
