As you can see, this is the Powerhorse 4500 case, not the Predator 3500. But all the parts are interchangable. And, the Powerhorse case has the RV outlet built-in. No adapter needed. It also has the cool start button and USB ports. I figure there would be some Predator owners that wouldn't mine those upgrades.

This case is from a NEW generator and includes everything pictured. It does not include engine, inverter, muffler, digital display, voltage regulator or 30 amp circuit breaker. If your generator has a damaged case and you need a replacement, here is your opportunity to upgrade. Notice that these new cases include a fuel gauge which was not included on the earlier models.

If you have any questions about what is or is not included, please contact me using "Ask Seller a Question". 

Thanks!
