I like your play on words, “Demonic” indeed! Sold my DPll 11K for $600 as well on FB Marketplace in short order.

Understood, I never had a leak issue with my Dometic either nor too concerned about being “dead level”. Some however, have not been as lucky!

This may be of concern to some, but we no longer have to worry about clogged condensate drain lines or drip pans causing leaks inside our units, which both Dometic and Truma owners have experienced. After a year of use, I find no issue with the roof runoff.

Agree, but understand the owner manuals are universal and state that some units may not have all of the features described. For example: “X-FAN function is only available on some models.” Furthermore, typical air conditioning is the Cool Mode setting wherein the compressor will regularly cycle to maintain a desired temperature and the supply fan runs continuously, which causes humidity spikes when the compressor shuts down periodically. In Dry Mode the compressor runs continuously for the sole purpose of condensing moisture-laden air to reduce humidity. Yes, this mode will chill the air much like Cool Mode, but since the compressor is set to run for a prolonged period the temp and humidity will continue to drop to such a point that it exceeds its function and thus, should then be turned off and the unit switched back to Cool Mode. Before Cielo, I had to use the Dry Mode to buffer occasional humidity spikes during the day, but when asleep at night I would often wakeup to extreme humidity levels at morning. The Cileo’s ‘Comfy Mode’ solved these dreaded humidity occurrences, both day and night!

If not damaged beyond repair, ask for a significant price reduction/refund and make do. Just say’n!

I am still amazed at the efficiency and cooling power of the Atmos and glad that SDG adopted the Tosot as an in-kind replacement unit due to tariff-related issues. I did not opt for the Cielo Max Breez thermostat being offered at the time of my purchase, even though it was widely used by SDG in their typical Class B RV installs. I have since added this device and find it extremely beneficial in energy savings, comfort and humidity control. If you didn’t opt for the Cielo with this a/c upgrade I would highly recommend adding one, you won’t be disappointed! I think it is also worth mentioning that these 15K units are far superior to the DPll 11K formerly in my OLEll, which was often found marginal at times during extreme heat conditions here in Texas. I was really disappointed to learn after initial purchase that Oliver began putting this smaller unit in the 2020 year model and thus, always my intent to upgrade to a bigger and better unit. No regrets in my choice and certain you will feel the same!

I see a visit to Greenland in your near future!

When using the Cielo Breez Max phone app, the actual a/c remote ‘must’ be turned off. However, the touch screen can also be used in the absence of Wi-Fi, but many of the advanced features (think Comfy Mode) are unusable. When using the unit’s remote, it is suggested to aim it at the Cielo rather than the a/c’s distribution/control panel. Regardless of the control method, the Cielo will display room temp, set temp and humidity level.

To be clear, the above statement was made in reference to the stats for a hammerlock product I purchased and featured in my comment posted May 11, 2025 of this thread. The ‘link’ being referenced in the above statement was provided by @jd1923 in his November 13, 2024 comment and the stats are for this dissimilar product.

Typically the DC-DC is installed in the trailer as close to the battery bank as possible.

Having the fan turn off as the compressor cycles off definitely prevents the dreaded humidity spike that many experience!

I suspect the “numbers” will increase somewhat as the compressor will work harder to reach and maintain temp in ambient conditions. However, likely less than what is typically seen with conventional units.

It will be interesting to see compiled data once your unit is tested ‘outside’ of the Vault’s climate-controlled setting, while camping in actual heat and humidity.

A good way to check if the GFCI on the inverter is working is to see if the microwave has power, since it plugs directly into the GFCI outlet on the inverter. If the microwave has power then your inverter is working. If not, the GFCI has tripped and needs to be reset. For reasons unknown my GFCI has tripped, wherein the microwave and outlet receptacles have no power. There have been times when it took a few presses of the reset button on the GFCI to get it to work again. Once power is confirmed at the microwave, all is good. This may not be your remedy, but a good place to start.

I tend to agree, and venture to say likely a bad ‘blue’ wire connection either at the male 7-pin connector or downstream on the Oliver. The OP has no issue with other trailers being pulled by his F350 and thus, don’t think the vintage of the TV or inherent factory installed equipment issues are of concern.
