Let's say 1 A/C unit is pulling on the 30A feed and the other is pulling on the 20A feed. Depending on your A/C unit and what else may be on that leg you may still pop the 20A breaker.

That combination will give you 50% of the power you would have with a standard 50 amp service. So even when using that, you may still have issues running two AC at the same time.
Basically, a 30 amp service provides one 120 volt 30 amp line. A 50 amp service gives you TWO 50 amp 120 volt lines into your rig. Inside your rig, half (approx.) of your 120 volt outlets appliances, etc utilize each single leg of your 50 amp service. So each AC would be on a separate leg coming in.
Using the plug pictured above gives you 30 amp at 120 vs 50 amp at 120 your normal hook up would supply. The other side gives you 20 amps at 120 rather than the 50 amp at 120 your normal plug is supplied with.. That being said, you have to HOPE that the 30 amp plug and 20 amp plug are not wired on the same leg coming into it's box. If they are... well.. you will have issues.. it won't work.
Bottom line at best, you may get 50 % of the power you would normally have available when using your standard 50 amp plug.
As said above, it's about adapting...being aware a hair dryer may trip the breaker... Good luck.
