We've had Honda generators for at least 10 plus years and really liked them. Mine were often hard to start but once started ran wonderfully. As with any gas generator making sure the fuel is stabilized and the generator ran at least monthly throughout the offseason(winter). I just purchased a new TC and decided to go with the built in Onan propane generator 2500. After adjusted properly when picking up the camper in October very little vibration but noisier than the Hondas however,those were not built-in. I have had gas and propane generators in our fifth wheels over the years currently a Onan/Cummins gas 5500 in our Jayco. The convenience of pushing the button, not worrying about theft, easier maintenance and no loading/unloading each time is worth the slight increase in sound and thus our decision to go with the 2500 propane Onan generator on our current TC. I do not have plans for running the generator all day merely spot use similar to other posters however, if necessary, I would use it all day.
