This version is more suitable for street driving than the previous one, but again, I would use it only if your vehicle is a track animal.
Moab, honestly, is really not challenging for the majority of engines, especially for B58. You are not dealing with extreme altitude and high RPMs for prolonged periods of time. B58 has an overkill cooling system. So regardless of the ambient temperature of 105, at 4,000ft, the question is whether the cooling system is sufficient and it is in your vehicle.
As for oil, IMO, you don't need for Moab 300V or Redline. I personally would get Castrol Edge 0W30 from local Advance Auto Parts and call it a day. Many people underestimate street oils. I ran Mobil1 0W40 on track to 300f, and still did 5k OCI. I ran Castrol 0W40 on track for 1 1/2hrs without stopping at 101f ambient temperature at 5,000ft altitude, and it is track, if I am not cornering, i am at WOT. I did 5k OCI and UOA still returned results on par Castrol Edge 0W30 that I used in winter conditions (Here is UOA after this post).
300V will have additives that are working great at very high temperatures, but during warm up or lower oil temperatures, it won't provide the same level of protection, cleaning abilities etc. as normal street oil. . So OK, in Moab, hypothetically, it will work OK. But in regular driving, oil might leave more deposits in an engine as additives that are used are specifically designed for really high temperatures for prolonged periods of time. I get that price is not an issue, but I am strictly talking here about performance.
Amsoil, like many others has a nice short article about it:

From my understanding, transmission is far bigger issue during extreme off-road than the engine is. I did not do extreme off road, just light to moderate stuff. I would be more focused on transmission temperature and cooling capability.
Now, will 300V destroy your engine? No. If it makes you feel better, run it during Moab trip. But once you are back and using truck for normal daily stuff, I would use normal oil, or change to normal oil during winter.
Here is my UOA of Castrol 0W40 that had extensive track use, sessions as long as 1 1/2hrs, which is really unusual, and Castrol edge 0W30 (one with 4,600mls OCI) used in winter conditions:
