Storage, furnace, and diesel burner

[Mark71]

Going to leave coach for 10 days, outdoors and plugged in to 50 amp. Overnights expected to be in low to mid-30's while away

I will set the thermostat to 50 degrees and "auto" in both zones.

Would AC2 be sufficient? Or should I turn on diesel burner as well for the furnace on those nights in the low 30s?

If I turn on diesel burner, it will only be using diesel when the furnace comes on during those overnights w/ temps below 40 right?

Thanks for advice and suggestions

Your diesel will be primary so I would just use the electric which should be enough to keep it warm.
I've done it and it works well. I would not use auto unless you want your heat pumps as primary. Below 34° your oasis would take over from the heat pumps. In short, your electric elements in Oasis will work for you.

Typically, if the electric elements are enough in cold weather, the furnace fans just run longer because the coolant is getting hot enough. It won't hurt anything. Since you have the temp set so low, it should work fine.

A power outage would be your only issue. If it's feasible, you might want to set the Auto Gen Start as a back up.

Got it. Thanks to both of you.

We set front zone to Furnace 73, rear to HP 70 oasis with both AC on. We were fine when the outside temp went to 25 for the night. No monitor how long it dropped, but that was the overnight low.
