Heeling ? These compressors typically allow up to 30 degrees of heel. The same as the icebox conversion kits from frigoboat, dometic, seafrost, designed for boats.
We have an Iceco cooler. Eventually, to save space, I plan on cannibalising it to convert our built in icebox. It has a better compressor than the seafrost kit I had originally considered.
I would consider an Iceco model over Dometic. Iceco uses a Danfoss compressor with a good warranty and the chassis are well made, but cheaper than Dometic. FWIW: I prefer to support smaller companies that make good products. I hate Dometic almost on principle alone.
As for Mobicool models, the ones with Samsung compressors are reliable, based on the small sample of boats I know that have them.
I spent 2 weeks on a friend's boat last summer. (It was a good choice on my part. We ate like kings

)
He uses 2 different Samsung based Mobicool units. A bigger one for a fridge and their smallest model for a freezer. This minimised airspace in the freezer and reduced how often it was opened each day.
