The one concern I would have is the lack of a 120v 30a RV plug. The standard outlets on it are rated at 13a. Will that run your AC?
The Champion 3500/4000 is a generator designed for RV use with a 30a RV outlet that not only doesn't require a adapter but also allows for all of the power of the generator thru that outlet. That way you can run anything on your rig including the air conditioning.
Other than that the Predator generator looks similar to a Champion and I bet it has close to the same noise level of 68 db.
