The biggest problem with the Truma is it is a slow heat system. It can not handle large temperature changes or that much even quickly recover from leaving the door open for a few minutes....
That's an accurate description of the Alde underfloor combo system, which provides a very even but relatively slow responding heat flow. But the Truma Combi is different, and much faster responding, providing the full 14000 BTU/hr output within minutes (20000 BTU/hr for the more powerful Comfort Plus version).
And that's actual thermal output, whereas traditional RV furnaces list BTU rates using gas consumption value where 20k BTU/hr gas consumption provides about 14k usable output at 70% average cycle efficiency.
Water heating on the Combi is a bit slower, but there's a Boost mode available for quicker hot water output.
