Hey everybody - thanks for the responses. So, armed with the new info I have a couple of follow up questions;
1) Compatible Trooper parts I'll try and get; half shafts, ABS module, wheels and skid plates. He also has a newly rebuilt engine with only 20k miles on it. Thankfully I don't need an engine but if someone else does let me know.
2) I think the Trooper wheels are 16" so if I can get those in the deal I'll look at putting some 31's on them. Does anybody know if they are the same offset as ours?
3) I was looking at the Rocky Road sliders unless I make my own. I prefer to have them bolt on. I really don't want to weld to the frame if I can help it and according to Rocky Road theirs bolt on. (Like your idea on the hitch Joe but I'm going to fabricate my own hidden hitch style).
4) It looks like the opinion is split on the hand brake. I want to confirm the concept though. My understanding is that the rear left wheel is the drive and the rear right is the slip? In other words, if all four wheels are stuck in the mud then the left rear will spin and the front right one? Then, if the left rear experiences "resistance" the diff engages the right rear? I know that's a bit simplified and obviously depends upon good clutch packs and components.
I really hope I can make it to Moab. Another friend (with an 2013 Landcruiser) and I would convoy out together and probably camp. But, I need to wait until we get closer so I can arrange for the time off. As much as I am looking forward to roading in Moab I am even more excited about meeting all of you.
