Good info and thanks again. To start, I believe I will be going with a 32" tire on 18" steel rims so the rods should be an easy way to test that setup. If I get to a point where I feel like I need more clearance, or I'm absolutely destroying my rig, I can move to the GAP Tool/SYA/Rods mix. Most of my driving will be through dirt trails, plowed fields, and light stream crossings, so I am not to worried about really high clearance at the moment.
Who knows what the future brings, though. Thanks to everyone for your input!
