OK, I believe you.  I was never, even when it was new, able to get better than 30 degrees put of it.  I weren't to the dealer (Dometic - VW wouldn't touch it) who showed me the spec sheet which said the unit was only capable of -30. After that I used it for storage, then finally pulled it. It's now in my storage shed.

That's marginally adequate in 70 degree weather (like in the Black Forest), but not so good in about 45 of our states this time of year.  I installed extra fans inside and out after cleaning and resealing the firebox, etc. before taking it out and gaining much storage space.
