Shore power

I'm interested in adding new shore power plug so I can separate Airstream trailer power to have a couple new circuits so I'm not sharing so much power when wanting to run Heater and dehumidifier.
Has there been many people do this. I realize I also have plug on the front of trailer but like I said I don't want to alter existing wiring. Already you have to be careful with the 30 amps coming into trailer.

Thanks for any info related to this. George

Not 100% sure if I'm following but this is something I did for pedestal use.

30A plugs in like normal.

I added a heavy 15A extension cord to run a ceramic heater. It doesn't interfere with normal trailer 30A power circuits.

Each trailer has it's own design and that's were things need customization. On my Classic I ran the cord thru the same hatch opening as fresh water, cord is coiled there when not in use. Plugs into pedestal. Then behind the lav sink and into the drawer under the fridge. Cord terminates at a duplex box.

What's your concern with "sharing so much power" as you put it?

If you're trying to reduce the load on the circuit coming in, you can simply turn off the circuit breaker for your converter-charger, and turn off the refrigerator, electric water heater element and the HVAC thermostat. Then no modifications to your trailer are required. If you don't like using the heavy, more-expensive 30A cord, you can use something like what I use in storage, a pigtail with the trailer-side 30A twist-lock, and a 15A male plug on the other.
