What do you think of this 2008 F-450? I'm currently 17 and starting a company more oriented towards landscape maintenance and construction along with hardscape construction. Do you think this would be a good truck to buy for hauling fill, mulch, stone, trees, and to fulfill other landscape needs? It has a late model 6.4L diesel with 136,000 miles with a 6 speed manual transmission. Thanks for your Input.
