Welcome to the Army Green club! Your upfitting wish list sounds like mine. I can only comment on the SLIDERS at this point: I went with RSG, flat, grip tread plate, bumpout, powdercoat, and so far I'm happy:
RSG: I liked the design itself, but several other factors were very important:
Customer Service: RSG responded quickly to my emailed questions. Some vendors never even responded at all.
Promised Install: Simple flat-plate mounts bolted on to the sides (only) of the frame rails. Lots of detailed photos, videos, and install info online. No drilling. No stick nuts. No messing with the gas tank shield, just detaching and re-attaching the parking brake cables. No blockage of drain holes in bottom of frame.
Availability: On the shelf!
Shipping: UPS residential!
Price (February 2020): $874, minus $100 T4R member discount, plus $181 shipping: total $955.
My Experience: 1.) Arrived in just 13 days, despite being warned of possible 3-4 week delay for powdercoating; 2.) Install went flawlessly.
