Yes it can but you must be most careful.
You have 2 hot leads going to the 220 outlet plus a ground and in some case a return lead.
Many are just 3 prong and do not have the return lead.
I have a washer and dryer that are stacked and the dryer is 220 and the washer 120 and they use the same plug.
To split off to 1ea 120 outlet you need 1 hot lead (Black) 1 Return lead (White) one Ground lead (Green).
As stated in the previous answer, you should install a circuit breaker box and fuse it to 15 or 20 amps depending on your requirements. You can get an air conditioning
circuit breaker box for a modest price and use it.
As a precaution, outside receptacles should be ground fault protected (Dirt Floor, Camper resting on dirt, Outside, I would install a ground fault receptacle where you plug in the 120V cable.
If you go with 20 Amp, make sure all items are rated for 20 amp. I would also use a minimum of 12 Gauge wire.
If you are unsure, check with an electrician and of course your local codes. Be safe.
