I'd give KME a chance, and keep an open mind. They are used in numerous major cities from coast to coast, and have many repeat customers. The apparatus they produce are highly customized. They are not the same KME of several years ago, they've come a long way from what they were. Building for so many different customers coast to coast has given them a lot of engineering experience, and added to their research and development aresenal. It also allows them to have the capability and experience to accomodate such a large order.
Just because it's not a Seagrave doesn't mean that it's crap. Seagrave had their problems, in fact numerous problems, as well with the FDNY pproducts they produced. I think that it's a money-loser for Seagrave, and they want to be better off with smaller departments who want a high quality, legendary rig, or smaller contracts with unique rigs that are exclusive to them, like the Aerialscopes.
I hope these rigs, any rigs in fact, work well with the FDNY members and give them what they want and need to perform the jobs they do in some of the most brutal conditions for apparatus in the world.
