xGROMx,
I thought the same thing when I installed my first one. I personally don't like the model you've got. I prefer to install a standard 15KW unit with a NEMA 3 100 amp transfer switch. It means we have to run our own control wires and provide a sub panel, but the installation is cleaner. the preassembled model is very limiting (like your main panel has to be less than 30 feet from the generator. If you have any questions, email me. We are a dealer for Generac. I might be able to save you some money on future unit also.
