Hi there AlbertS I guessing you have figured out that most of the 10 ton trucks you have been looking at are basically regular passanger truck cabs.If your good at scratch building you can turn any truck cab into a heavy duty truck. Its rather simple to convert the cabs with altered fenders,hoods,wheel wells,rims and even lights.If your a serious truck builder then have a look at some truck forums out there you'll get all the info you need there hope this helps you and everyone else.
