As an RV owner, sooner or later you will learn about your RV electrical systems, usage and means of supply, due to the RV's limited electrical system.
Remember the old television show, "Green Acres"? How the husband had to number code all the plugs so his wife wouldn't overload the system again, as she did frequently. Everything was plugged into extension cords. Think of your RV electrical system like that, only with a more limited power supply.
Check with an electrician, you may be able to bump that supply circuit from a 15 to a 20 amp circuit breaker. A long as the feed line is 12 AWG, its normally OK by NEC code.
More data, better decisions. I again recommend the Kil-A-Watt meter. Using a regular 15 amp plug extension cord with the 15-30 amp cord adapter near the RV, you can monitor power use of your various gear and check for excessive voltage loss.
For all, there is a plug in digital voltmeter on Amazon for about $10. I put one in the power strip beside my door so I can see the voltage when I walk in or out. No outlets near there ;(. My EMS is under the dinette bench by the TT power inlet and I was too cheap to get the remote read version.
