The Prodigy itself seems to be a great help in slowing my car carrier behind our class A diesel. The proportional braking is much better than delays and other solutions. If you have a truck or RV with an OEM controller adapter pre-wired by the manufacturer terriffic. The free installation notwithstanding the installation only involves plugging in a wire harness and screwing the bracket to the dash somewhere where the unit is facing exactly forward and at a reasonable vertical angle (see the instructions). If you are not at all mechanically inclined Camping World will do it in about 20-30 minutes. However, if you have them do it watch them closely. My store (Tampa) put it in at an angle of about 30 degres from straight ahead and the manufacturer told me to move so it is really straight or it might not work right (which you probably won't know until you lose your tow). It was also placed such that I could not see the display without hunching over the steering wheel. I have since repositioned it myself so it is straight and visible. Also, the CW "free installation" is only if you are pre-wired. If not, look for two to four hours labor and parts (wire, connectors, etc.) before than can install it "free". If you already have a 7-way plug at the rear you are part way there but they still need to wire the unit in under the dash. Make sure they are clear about what they are going to do before you sign the work order.

I have used cheaper brake controllers & after owning the Prodigy I will never go back. This is the best investment of any camping gear I have ever bought. It is so smooth when you come to a stop plus you don't have to cut it off when backing up. I pull a 30' TT with an Avalanche & it works perfectly. After the initial adjustment, which is very easy, I haven't had to touch it since. On the old one I cut it way down around town & cut it up at road speed. You will not regret the little bit of extra cost, it is worth every penny.
