Does Anyone See A Need For a Portable Generator?

If the Generator was overloaded, it should have tripped the output and got a warning light on the set. We have a gas MH, and carry a 2K generator, even though we have an onboard 5.5 gen. The 2K will run for 6 to 8 hours on a gallon, the onboard uses .9 gallons per hour. If is is hot, we use the onboard gen as the 2K will not start either AC unit. We use the 2K when watching TV, be it Sat or DVDs. We have Solar, but they are aging out and their output is getting lower each year.
