Cirrus 820 heating while driving

Eugene

When driving from one destination to another in below freezing temperatures, does the Alde system still work on the electrical feed from truck alternator to maintain an above freezing temperature so lines and tanks don't freeze?  I have the standard single Battleborn package.

Short Answer:
 - -  Adle will need Propane to operate while driving
 - -  Propane supply, Not Electrical power
Is the critical factor.

Long Answer:
If the Alde is set to 'Heat Source' Propane  & 
the propane burner is not blown out by road driving wind  then . . .
Yes, the Alde will run and keep the slide-in camper warm.

So, what you are proposing is doable If you use Propane.  The Adle can operate on 120VAC or Propane to create 'heat' . . . the  truck/battery 12VDC is only used by the Alde Control PCB.  That DCV load is well below what your truck will be able to source to the camper.

There are lots of pro/con opinions on the benefit/danger of operating propane heat while driving . . . you need to decide your safety comfort level.

Side Note:
   A few years ago while winter season camping in a 320S, I forgot to turn the Alde Off before hitting-the-road and was [pleasantly] surprised to find a very comfortable temperature TAB at my first Rest Stop as the Alde worked fine and in that drive the burner did not blow out - - - my issue/concern was propane usage as trailers only have one tank (don't you have two?)
