Yep, we are close to Selma. I do see Troopers on the roadside pretty routinely. 281 is a good alternate to I-35.
As for the belly panels, I have successfully used nylon tie-wraps, bailing wire, metal screws and brackets to secure various test panels in place. Self-adhesive velcro did not work. Duct tape doesn't hang on very long either. Packing tape does better.
I fabbed brackets from the front lower frame all the way back to the rear axle, plus a couple on my nerf bars to hold side-skirts on, plus a few more to hold my wheel flares in place.
I've used a couple of 3x4 pieces of .050 aluminum for the eng bay and under the tranny, but I really need to cut a couple access panels in it for oil changes. Although, I plan to replace the eng bay panel with some 1/8 ABS plastic.
