I didn't see an off road section, so here...Here's my thought, I got a 78 3/4 ton with tired 350, sm465, np205, dana 44, and 14 bolt and no lift-yet... Looking to fit 38's under it and wondering if I ought to just trim them fenders to keep 'er low and mean. Anyone else done this? how large a tire/lift combo does a guy need? How wide a trie/wheel? Looking to make it a mud masher not a street streaker. Any help?
