Well, that is what a lot of the mfg's suggest. The load is to get both the engine and the generator warm enough to drive any moisture out.
Actually just running the engine long enough to get hot will drive out any moisture, load or not.
In my opinion I believe the load test exercise is to check whether or not the "governor system" is working to provide stable power under load. In other words, does the engine automatically supply enough throttle to maintain 120 volts and 60 cycles as the load changes?
The thing is, unless you also set up a meter to measure the exact voltage and frequency, all you are really doing is just running the generator and seeing if it powers anything. You have no idea if the frequency is correct or the voltage is stable.
Commercial buildings that have generators do not run their generators under load but they do verify that the engines start and produce power.
