To the first, yeah, I plan on adding sliders soon, probably Road Armor or Smitty Built. As to under skids, nothing that isn't factory yet. I do have a front skid, but nothing for diff or tank yet. I try to not get myself into any situation where I would damage those, but accidents do happen, lol. Mainly, I take my time, either walk or use my drone to scout ahead in anyplace that looks like I might have an issue. I've had to detour a few times on the Transamerica Trail because of this. One day though. I agree that it is hard to find anything for these years of trucks. There is always custom fabrication, but that is usually expensive unless you have the ability and tools yourself. As to the rims, sadly, I have looked hard and long for a fifth one, but those are 20 year old Ultra Wheels that were discontinued about 15 years ago. I switched from the 18" stocks because I knew I'd be going off-road and everyone told me to loose the aluminum rims and get steel. I can't justify $1,500 for rims. Hell, I only payed $2,500 for the truck itself, lol. I would like to get another though. She's about 90% done. Want to upgrade the RTT to either a pop-up or clamshell. With how I have it mounted with the side and rear awnings, it's a real pain to set up everything. I have to carry a 6 foot ladder to reach everything on the top. Granted, I have the room inside the topper, but I've learned over the years that the less you carry the better. :)
