I bought the generator from a local retailer for a good price, but found that horsing around a 100 lb. generator in a "lights out" situation was not something I wanted to do, so I ordered the wheel kit from Cabela's. Installation was fairly straightforward, except for the handle. The design is not would I would call "intuitive." In fact, it is weird, and the instructions are inscrutable. But once I figured it out, it went together easily, and works perfectly. The wheel kit makes a BIG difference, and I highly recommend it!
