Thought I'd post a little update.
I still have a laundry list of little maintenance tasks that need to be dealt with on it. I generally dislike working on my truck any more, so that makes it difficult. However, I did work on it this weekend in an enclosed space with flat ground, out of the weather, at the barn where I have all my tools stored, and that made a WORLD of difference for my morale. Having all my tools handy, and staying out of the weather really helped. I'm feeling motivated to get more stuff done. So that's good. We're trying to find a house to buy right now, and once that happens it will help immensely with my interest in working on my truck. Right now we live in a 70 sq. ft. room behind my in-laws' house. We remodeled what they used to refer to as their "potting shed." Actually, I love the little hut we live in and wish I could take it with us when we leave, but I'm very ready to have my own space for Claire and me again...
Some of you may have seen my post in the Garage wondering if my Detroit was failing me because the rear end would bind and buck and bang when I drove it in reverse. I spent a bunch of time trying to figure out what was going on. I pulled the diff cover and changed the fluid to check things out in there. I did the work on a hill, overfilled the rear end, and blew out the black RTV sealant the very next day.

Couldn't find the problem. Really pissed me off. Finally I realized that the stupid shop that put my new catalytic converter in didn't attach my rear exhaust pipe hanger, and the pipe was sitting on my tire. In reverse it would bind up against the tire and cause all kinds of problems. They put a new hanger on it (which was pretty crappy work, IMO), and the problem is gone. So that was an easy fix, I guess.
I resealed my diff this weekend, and that went really well. I had also discovered that my rear cargo carpet was water logged, and since it was so nasty I decided to just pull it out. As a long-term-temporary alternative, I cut up a shop rug and put it in there. It's water proof, and resistant to oils/solvents, so I think it'll be a good solution for a while. I'd like to do bed liner back there and then put a new carpet kit in someday. Let me tell you something, though: Seeing near-pristine sheet metal under that carpet was really enjoyable and very motivating to getting on top of my maintenance list.
I have one really significant problem, however. It appears that I may not have sealed my intake manifold well enough. If my truck sits for a couple of days unused, it smokes pretty bad at start up. It stumbles a bit at start up too. It's white smoke, but it mostly just smells like unburned fuel. I checked my coolant, and the radiator was half empty.

I did an oil change and saw no evidence whatsoever of water in my oil. So I think there may be a pinhole leak between the coolant passage and one of the cylinders. That's really frustrating to me. So, I gotta find the time to pull the intake back off and reseal it.
