First post on EP. Hello!
You guys just missed it - a New Jersey fire department raffled off the gray AEV Brute for $100 per ticket. The drawing was held in early October, and it was won by a gentleman in Maryland. They had 2000 tickets for sale, and only around 1000 of the tickets were sold, making the odds of winning relatively good.
During the raffle, I had a good bit of exposure to the Brute. The overall quality of the conversion was still very high, but certainly not without its problems due to the complexity of the vehicle. These small problems aside, I would still love to have one, as AEV does great work.
To my knowledge, only 2.5 Brutes exist. There is the red one, that I think may have been disassembled to an extent, the gray one which was just raffled off, and a yellow one owned by Hi-Lift that you may have seen at SEMA.
