John,
I would love to go to the meet, but it is about 400 miles away.
As for the tanker body, this summer I'll be removing it from the truck and probably listing on ebay. I've been watching for a nice 12 foot stake bed for it, but have only found good ones in Florida, California, or some other place a thousand miles away.
I started the Onan pump last week and it ran fine, but I only ran it for a few seconds since there was no water in the lines. When I negotiated the deal on the truck the fire department kept the siren, light bar, gumball light, hoses and hard suction hoses.
