Pop-Up Camper and Generator Question!!

[Wrangler95]

The cable that pulls out from the side of my camper wont fit my outlets on generator but it fits with an adapter in the 5-20r outlet which says household.Will this outlet power a TV,DVD player and a 60 watt light?Here is a pic of it plugged into this 5-20r outlet!!



Here is a pic of the RV ready plug that says TT-30r but none of my plugs fit this outlet.The outlet is way bigger than any of my plugs.Here is a pic of TT-30r outlet on generator.





Here is a pic of air conditioner plug that also doesnt fit any outlet on the generator.What kind adapters do I need for the plugs?
