Hi,
Check out their you tube videos. They do go into more detail.
I can tell you that at -8 C (17 f) the boiler temperature remains the same on my Dometic (with arp installed).

In their video, the temperature rises only around 3 degrees before the unit kicks in
How high does the temperature have to get for damage to occur? How much tilt? Over what period of time? How critical is it? How much does the ARP unit affect life expectancy? What is the normal temperature swing of an unmodified boiler? How much does ambient temperature affect the temp of a boiler?
Interested but skeptical until I can see a better case.
