Now it seems that Sportsmobile does say that their air conditioners can run off of their 2000 watt inverter, which I do believe is Magnum.
So have you talked to Sportsmoble? The magnum 2000 does have pretty good surge power specs. Dometic is not very good at listing their specs.
You need to make Magnum and Sporstmobile talk to each other. One is saying one thing, and the other the opposite.
What error is your Magnum displaying?
I see this as a option for someone with pets, that need to provide cooling for short breaks , as they are away.

I have a 13.5kbtu AC from Sportsmobile and 200 AHours AGM battery.
The 2000 watt Magnum will NOT start both the fan and the compressor at the same time but if I wait for the fan to come up (in the heat position) before switching to AC then the Magnum is able to start the compressor.
I have used the AC from battery for a short peroid (1 hr) to keep the cat cool while we had lunch.
So it is possible but I have a white van. It was cooled down already from the dash and rear evaporators when I stopped for lunch.
The roof compressor was cycling and the fan runs all the time.
I think it is a better idea to just leave the motor running with the dash AC on. I have a gas engine in my Promaster.
