  • Post in thread: Replacing a built-in Onan generator in a Class-A

    I now have a gaping hole in my 18-year-old, 31' Airstream Land Yacht where a 280-pound, 5500-watt Onan used to be. To shorten a longer story, mice got into the genset, chewed the windings to eat the insulation, and repairing/replacing the genset with another Onan isn't an option, primarily...

    Hi, Deno, that's the general plan. I just don't know the ideal ratios of power sources and storage for different situations. Everything has plusses and minuses. With Onan gensets, it's mice that can destroy all your hard work. With LFP, it's temperature. It's going to require some kind of...

    Hi, HighTech, It's a good point, i.e. combining the legs, but the issue has never been the running amps, it's the *starting* amps that get you, and in my case, I have two neutrals (#10 and #12) which run in different directions and won't handle 50 amps individually. However, they're a perfect...

    Thanks for the heads-up on Smokstak, Deno. I could still save the "core," but I told Cummins to scrap it, and that will happen tomorrow. It was more than just the stator windings. If I'd noticed the problem before attempting to start the engine, it might be different. I got it to run for about...

    Hi, HighTech, I can step down to a new 4KW Onan that will fit in the bay, but it: 1) costs about the same ($6K) because of mods for the different mount; 2) is wired to drive only one leg (one AC), so I still need shore power to drive both ACs; and 3) it's still susceptible to rodents, and...

    Yup, a barn cat would do the job. Bought this rig from a guy who had dogs.

    Thanks for the reply. A hitch cage is an interesting idea, but my max is a measly 300 lbs of tongue weight. Just found the batteries at Lithionics. Don't know the chemistry, but sounds like LFP. They're used on the Galleria. They've got 600-amp packages with what sounds like sophisticated BMS...
