I'm making an assumption here, if it's incorrect, then please advise. I'm assuming that your RV, a Hideout 27RBWE has a 30 amp shore power cord/power center. If this is correct, then your trailer can't use any more than 30 amps, so buying a larger generator won't help you. Essentially all it will do is make moving it around more difficult (heavier weight) and increase operating expenses (bigger gas engines use more fuel). It may also be louder, but the operating dB is not listed on the Sam's website.

Anything over 3500/3600 watts "operating power" is not going to improve your outcomes. Since "contractor generators" all operate at 3600 RPM, you'll be at "max capacity" as far as the engine is concerned as soon as you power up the generator. No need to "power up 4000 watts when you can only consume 3500, but if your trailer typically consumes 3500 you won't be satisfied with 3000, it will trip the circuit breaker on the generator as soon as you go over the generator's capacity.
