Utilizing a generator can take approximately eight hours and consume about two gallons of gas to run the RV air conditioner. If you require air conditioning but do not wish to consume a large amount of electricity, consider portable generators with a longer lifespan.

There are different generators available, including diesel generators, gasoline generators, and LP generators. As a result, the generator’s fuel consumption will be determined by the air conditioner you’re using and the duration you’d like it to operate.

Check for the best generators from Amazon.

Consider the following parameters when selecting a generator to use:

  1. Flammability requires using a generator that runs on somewhat flammable diesel fuel instead of gasoline or propane, which are highly volatile.
  2. Environmental impact: You should select a generator that burns efficiently but does not harm the environment. Thus, unlike gasoline or propane, diesel is still acceptable in this circumstance.
  3. The level of noise is such that users need to select generators that produce less noise, and keep in mind that diesel is the noisiest option in this scenario. However, when operating a generator at your home, ensure you close all windows to prevent noises from entering your rooms.
