What kind of truck, and what frame are you thinking about? The Trailfinder chassis kits are really nice. I had one, but sold it. Now they've got an updated TF2 kit, which is even nicer. If you are thinking about their 6x6 chassis, well, that's really a non-scale like chassis, and I don't think you'd see any scale tractor truck builds based on that, unless they are running some bigger then average off road tires. The Man F2000 chassis does not look all that different from the Tamiya style ladder frame chassis. I'd give the nod to the Tamiya, because it's more flexible in design. You can always get longer frame rails and make it whatever length you need.
