Generator Sizing
I have been looking for a generator for our TT for a while now and I have a question I hope I can get some answers to. My trailer will most likely need around 3.5k watts to run everything including AC...

Rich, there are generators and there are inverters. A generator runs at full RPM all the time (unless it's one that idles down with no load); an inverter runs at an RPM needed to support the load demanded.
Actually, both are generators. One is a synchronous AC (alternating current) generator that runs at a fixed (synchronous) speed determined by the number of poles in the generator and the desired AC frequency (50Hz or 60Hz). Synchronous speed is calculated as cycles per minute (3000 for 50Hz; 3600 for 60Hz) divided by the number of poles in the generator. For a single pole 60Hz synchronous generator, synchronous speed would be 3600 cycles per minute divided by 1 pole = 3600 RPM.
The other is an inverter generator that inverts DC into PSW AC at a fixed frequency (50Hz or 60Hz), leaving the engine RPM to float with load.
50Hz AC is generally used in many European and Asian countries - North America uses 60Hz AC as a standard.
