All joking aside I see at least 2 gallons, probably 3. Nason Ful-thane is mixed 8-1-2 so 2 gallons mixed will give you almost 3 gallons sprayable. You're gonna need 3 coats total, the first coat is gonna be a light tack coat, them 2 full wet coats. If you're too aggressive on the first coat, it likes to run.
I'd suggest painting the trailer in two parts. Do the nose and one side first, that way you'll get an idea of paint consumption and 2nd it will be easier to manage. I like Nason Ful-thane, It's affordable,holds up well and is pretty easy to spray. I love the single stage black, its deep as could be and looks wet.
