Wow, it's been a while!
Nothing crazy. Two oil changes, lubed up the power running boards, replaced a turn signal bulb. Up to 107,000 miles. Towed two e21s, an E30, an e82, an E39. Sold my open trailer and bought an enclosed.
The truck tows the enclosed pretty well. It's a lot more stable than my open was, but obviously way heavier. 24 box, steel frame construction. Fully finished interior with AC, rubber coin floors, upper and lower cabinets, 12v and 120v lighting, speakers inside and out, loading lights, and exterior side lights.
Picked it up for a decent price in Raleigh and had to reseal the whole roof. It needs a good cleaning inside and maybe some more sealing/repair, and replacement of things like some water damaged boards. Overall, the trailer is in good shape.
Butyl seal completely gone from the roof seams let in rain water in the roof, which then leaked down through the AC, the back corner (Rotting the floor), and up front into my cabinets.
Scraped off the bad sealant, left the good, and covered everything with Butyl Tape. Also patched the floor in the rear (but plan to eventually pull it all up and replace the whole board), replace some weather stripping around the door, and used butyl tape to seal up the trim at the rear of the trailer.
Things to improve on the truck:
Need to take it in to get the rear defrost issue diagnosed. I'm 90% certain the whole rear glass needs to be replaced, but I would like to get it confirmed.
Transmission has had an occasional rough shift every once in a while. Probably should have that checked if I take it in.
Power Running boards are slow, not easy to service, and some times they stick down.
Rear bed cover is starting to fall apart
Tailgate is hard to hopen
Tailgate trim is coming off
I need to get under and wire brush/paint/fluid film the frame again
I ordered some helper springs to install on the rear and managed to lose one of the springs while I was waiting on them to send me some missing hardware. If I don't find the spring, I may just order some bags.
