Just be aware that the circuit breakers on both your coach and the relatives service disconnect are probably 50A. which are designed to protect the correct gauge wiring installed for that service. A stretch of smaller gauge wire in between (30A ~ 10AWG?) will not have the same capacity. It will in fact be vulnerable and could overheat, before tripping a breaker. That being said, you very well may be able to accomplish what you are trying to do with "caution".
Another point will be that the 30A service cord will only supply potential to half of your coaches distribution panel (50A service relies on 2ea. 110V legs). Often multiple RV A/C units are divided with 1 ea. unit on each circuit along with other loads being equitably divided. So some items may not be powered as you might like. Many RV builders often wire the necessities on circuit 1 to accomplish what you're trying to do. This may included the fridge, lighting, and the converter to keep the house batteries up. Many users overlook the converter and it's amp draw.
It would be helpful if you had a load center panel / display that indicated your current draw per leg.

Yeah, a 'power panel' to show you if you are near a limit would be genious!
