    Portable Generator/Inverters

    I have read many of the posts, but am still uncertain about my options. We want to be able to run one 15,000K A/C, our residential fridge, and the TV off a generator. I am open to installing a soft start unit in both of the A/C--but we only run one at a time. Will a 2,500w generator/inverter give me enough starting and running watts?

    If I need to go to a 3,500w generator/inverter, does anyone travel with and run their unit at the back of the trailer on a cargo rack?

    We have a champion 3400 watt dual fuel inverter generator. It runs the 15k AC unit, although with it the Soft Start AC unit, it struggles when the compressor kicks on. (This is something I need to get for both my AC units.)

    We travel with it in the back of our 320MKS in a cargo rack. It is ratchet strapped down, and cable locked to the daddy l safety chain points on the trailer. I also bought a canvas tarp to wrap it in to keep it "clean" in weather.

    The Harbor Freight Predator 3500 is very hard to beat for your needs. Price, noise level and reliability are all good.

    If you want more power, add a second one and a parallel kit.

    We have a Champion 3500W Dual Fuel Inverter/Generator and always run it on Propane. We have no problem running our A/C unit with this generator for hours at a time. We keep the Generator in the truck bed and we run it off of a 20lb Propane tank we keep lashed down in the back corner of the truck bed. We actually run the generator in the truck bed from this Propane tank (obviously the exhaust is pointed towards the middle of the truck with no obstructions), we simply plug the camper into the generator.

    I truly believe this Inverter/Generator has enough power to run both your A/C unit and the Residential refrigerator simultaneously even if you are running it on Propane (it certainly will have enough power to run both if you are using gasoline).

    PS: we have had this Generator for a few years now and we really, really, love it !!!

    I run a Firman 3300 out of the truck box also. I love the remote start stop feature. I've had it for a little over a year and no issues. We have a smaller tt but I'm able to run every as if we were plugged in. Ac, fridge, water heater..

    A 3500W generator (like the Champion 3500 dual fuel, etc) will generally provide a 30A hook-up. Same with two 2K/2.2K generators tied together. in parallel That would be enough for one AC and several appliances - also remember that your converter will be drawing Amps as well when hooked up to the generator. With a single 2.5K generator... you generally get 20A hook-ups.

    I have a Generac 3000i and it runs a 15k A/C just fine. I have it mounted on a cargo rack off the rear bumper. I installed support brackets for the bumper and it seems fine like that however I have not travelled much with it yet.
    We also made a rain cover that can protect the generator when it's running.
    I had to modify the spare tire carrier to raise it up so part of the cargo carrier could be below the tire.
