Wow, good lookin!
I'm gonna sound like a snob here, but my opinion is worth exactly what you paid for it.
If I were you, the first thing I'd find would be proper suction caps for the steamer inlets (the 4.5 inch pump inputs). The hydrant caps on there now don't do the truck any favors. (there, I said it. I'll shut up now.)
Then, a proper wooden extension ladder to hang on the captain's side - you'll be amazed how proud you are of it when you get one!
Truck looks like it's in fine shape. Military truck originally? What engine, the 216 or the 235?
Welcome to the stovebolt site, great people here. Hope you enjoy your truck!
