I wasn't concerned about the age, but the type of vehicle it is. I know for a fact that NY will not title or register my landlords old 1977 Mack dumptruck historic. Once you get above that magic 26,000 pounds with airbrakes, I think you will have a hard time convincing Motor Vehicle that it is a "Historically significant" vehicle. The class I had to take to drive and operate ARFF units was 2 weeks long, and I already had my CDL for years...BTW, they drive like $h!t, horrendous body roll, less than 1 mpg, terrible brakes, but then again, the one I drove had 5000 gallons of water and 400 gallons of foam mix in it. It was a 6x6, could have used the extra braking axle... Might not be too bad if it was always empty. Gonna have to strip the deck guns off the roof to get it under 13'6", got to cut something off the overall length somehow to get it under 45', no way to get it under 102" wide...
Don't get me wrong, I say give it a shot! I just wonder about getting insurance for a 130,000 pound, 50 foot long, 14 foot tall, 10+ foot wide, 8x8 fire truck with big placard on the dash that says "FOR AIRPORT USE ONLY"
