Working on converting this beauty to a camper van. I am having a tough time figuring out who converted this...it began its life at McMurdo air station where they outfitted it with transmission and engine heaters and a bunch of other random features. Front looks like a Dana 50 4.10. BW1356 transfer case. Any help on figuring this thing out is appreciated. I know very little about 4x4 setups. Thanks in advance!
