With the extra adapter I assume the splitter is 2x 30a to 50 amp. This will not combine power. Actually you are drawing power from only one side of the 50a and likewise from only one cord.
I don't think amps is the issue as much as voltage. Those extension cords look a bit thin and maybe too long. Red cord is maybe OK but should be #12 wire minimum. Check and monitor voltage in the RV. You are looking for 108+ when running. Post your findings.
Use a 20/30 adapter and plug the rig into a 20A plug especially a dedicated 20A plug and the A/C should be OK. Or use a 10 gauge extension cord as short as possible and not those more common extension cords in the picture.
