ton of fun. I only have wheeled the 'Con with Buggies, so I do take a bit of rash.
IMHO, no way that truck will make it. the 10B's are the first issue, lack of uber or stupid low is another. Lots of ledges that my TH350/NP203 would have died on. and even with 40's I had to bypass Little Sluice. Old Sluice and Big Sluice were no problem.
And the "pop it out and drive out in 2wd" is a bad joke. We headed up one time to help rescue a guy that forked his front driveline. That was more then I bargined for. he got out, but the rig took on MAJOR damage.
MY GF has wheeled my junk through some of the rough stuff there, but that was the truck doing a lot of the work. She got it through gatekeeper no problem, but tried it in 2:1 then had to slap it into 4:1 to make any progress.
The other issue is if you go all the way through, you have to be able to drive it back around from NV into Callie. so a munched rig wouldn't do it.
Noel had a buggy on 1/2 ton gear. super light, super flexy, and he was breaking shafts. We brought him one from Iceman for his 12B.
If you still insist on doing it, do it during the week or on a uber slow weekend.
