New trailer, new generator?

Hi, we just upgraded our TT from a 21' to a 28', we currently have a 2000 (1800 running) Yamaha inverter generator. I have a feeling that this little gennie won't supply enough power to run the new bigger trailer, what wattage would be recommended for the larger trailer?

Thanks
Brian

  • Unless you wish to run the air conditioner there is no need to upgrade the generator.

    I want to be able to run everything, my little 2K would'nt run the AC in our little trailer.


    A good ole reliable Champion 3500 would work for you and not break the bank.
  • Verify the new rig's AC unit. Some newer ones do not require as much power as older ones.
    Yes, a 3000-3500 genset will run everything.

    Really no difference based on trailer size. The power demands are going to be about the same until you move up to dual air/con RVs.

    You can jump thru some hoops spend some money and maybe get the 2000 to run the air/con.

    I would recommend something in the 3000-3600w range. That's generally going to be plenty to get the air/con started and not be crazy big.

    Keep an eye out for sales. Last year found a Champion Dual Fuel 3200w for $650 for some friends.

    I put 400 watts on my little trailer, gonna miss it! I do plan to eventually run Solar on the new trailer.

  • ...and adequate batteries, time.

    Still run into RVers who think solar doesn’t really work.
  • If you aren’t running the air conditioner, your generator will be just fine. Solar is easier but old generator will do it.
