man, I love the old iron... Can't believe how your riding the old girl, lol, but heck, looks like she was built for it, so enjoy! curious if you drain the diff's after an outing like that?
What's your "20"? Canada?
I checked the diffs and there is a little bit of water contamination but it isn't too bad. I do a lot of long trips so I figure most of it will evaporate once I heat the diffs up... if it doesn't I will change the fluids sometime when it isn't so cold out!!
