I bought a Lenox hole saw, but the same store didn't have any lubricants besides WD40. So I'll wait and go to Home Depot tomorrow... right before I hit the RV show!
In other news, I cleared out some more of the bus after work today. The bifold couch is gone, most of the luan wood paneling along the walls, and that big metal tool cabinet (and boy was that thing heavy!). The tool cabinet had a ton of goodies in it, which I sorted and stored in some old shoeboxes I bought from a thrift store yesterday.
Oh, and I also replaced the buckle on the driver's seat belt.
Looks like the bus may have the typical window leaks. I'll have to get into the metal sides and make sure there's no rot.
And, before I drive this thing again, I bought some fuel conditioner (the 911). A "water" warning light comes on every time I crank it up. I bled the air tank and there was no water in it, so it must be fuel. Once the water problem is fixed I'll go back to using the diesel kleen that the previous owner recommended.
More details in my blog.
