Rock crawler

Time to make a decision. Complete build of my 14 xp1k to rock crawler or trade for turbo. To complete rock build I will have to install turner gear reduction and reverse chain while I’m in transmission. This will be 2500 or so. Already have skids tires high clearance suspension parts and upgraded shocks. Would even think about trading if all accessories would not swap to the turbo. Main reason to trade would be extra power at altitude of 10 to 12 thousand. Upgraded drive train should stand up to crawling. Anybody with experience with both machines in rocky terrain such as Moab Colorado or smorr type trails
