Damn, just watching that video makes me want to smash my fingers with the ball-peen hammer, I couldn't imagine driving it!!!! Just kidding......I love the leaves and crap falling off it in the first few seconds of road time. Gotta be a good feeling getting that thing out there for the first time in almost 10 years, I'm sure you have a list of things to do......Obviously from the video though make sure you go over all the running/brakes lights. Hopefully you just have to do light bulbs. Having someone hit the alternator with a tester couldn't hurt if you know someone with a tester. Scrape down that 5th wheel, get rid of all the old crud, then steam clean the entire ass end, especially the 5th wheel....Then maybe hit it with some sandpaper, and then re-grease it with fresh grease. Then crawl under the thing with a creeper and a grease gun with a full cartridge, and hit every grease zerk you can possibly find. And change the crankcase oil ASAP- that should be the first thing you do in fact- Detroit recommends using straight 40W oil which breaks down over time......I have had several oil people tell me to never allow straight weight oils to remain in a crankcase (or even in bottles on a shelf for that matter) for more than 2 years.
