    3. Over sizing your wires is an investment in safety and efficiency.
    4. Vibration! Damaged insulation is pure trouble.

    What did I leave out?
    Certainly you point out that’s where resistance and heat start fires in many cases .That’s true HOWEVER cheap batteries made with poor quality control have the potential to have a thin barrier between components in the LI battery. Vibration can damage them.

    I know the LIP04 are much safer but please don’t tell me the wires started the fires in the planes or cell phones. A LI fire is very very intense. And even if the fire starts in the wires/ fuses, if a LI battery is present to burn or ignite from that the risk is still there.

    It is a great setup. One thing you could upgrade is those flexible hoses GD uses, I see one coming off your water pump. With all the $$$ in electronics right there, it would be a shame to have a water leak in that area.

    That wall is in place when driving, was just out for this pic due to work I was doing. I expect at some point I will replace all the cheap flexible hose with PEX, do it right.

    On another forum one of the highly recommended mods is to isolate the water pump for noise reduction using..... wait for it...... Flexible hoses. I actually did this mod on my last TT. It did cut down on the noise a good bit. My present GD has a very quiet pump. Can barely hear it. Of course it has flexible hoses from the factory.

    A good point. They use the flexible hoses in many more places than to/from the pump though

    This would be fine with the correct fittings/hose combination. But GD's use of flexible hose and PEX fittings is not the correct combination.

    Why are you considering a 240v Mini-Split?

    Wouldn't a 120v system be better?

    I understand your desire to upgrade to the Mini-Split due to efficiency and lowering your Camper height by almost 12 inches. I am surprised Manufacturers are not offering Mini-Splits as an option, well, not really that surprised, but Mini-Splits are a good option for RVs.

    I have had 3 clamps ooze water so far. I went and bought the expensive tool for installing the clamps. I just recrimped them. The leaks stopped. Every fitting I checked was not tight enough. Reading the instructions for my expensive new tool, it states that the tool will need perodic calibration. There is a special gauge and instructions on the procedure. My tool being new passed the gauge test.

    I wonder how often the tool the factory uses gets calibrated?

    Not saying that my leaks will not return..... But the clamps were for sure not tightened to spec.

    The 240v units are built more robustly, more efficient, and function better at the larger sizes. Since I would want a multi zone unit, a 120v unit just doesn’t seem like a good fit, for a single zone, sure.

    Fortunately, I have proper 240v due to my power system so this IS an option for me.

    I agree the rooftop units are an utter joke and offering a mini split from the factory should be perfectly doable and would work great. I saw a video of a New Horizons unit with one optioned in (in a $200k trailer....) but other than that it seems no builder seems interested.
