I asked for a Prodigy to be installed in our truck but got the new P3 instead. From what I can tell on the box and on the
www.tekonsha.com website, it's the same as a Prodigy with a different face and user interface, plus it will control hydraulic trailer brakes as well as electric. I think they called it either "electric over hydraulic" or "hydraulic over electric" brakes.
The dealer said same price for both. I'm not sure if that's because he had the P3 in stock and maybe not the Prodigy or what. Anyhow, since many of us have recommended the Prodigy in the past I wanted to note that there is a new kid on the block. I'll find out tomorrow if it works as well as the Prodigy but I'm sure it's the same basic unit.
