Convert to 50 amp
I have a 30 foot Hornet travel trailer on a lot in Florida. It seems the 30 amp feed is barely adequate for the rig. If the a/c is running, using the microwave will usually trip the breaker in the rig...

You can buy an automatic load shedding device but aren't cheap. You could make your own up by using a CR Magnetics current sensing relay like in the photo, available on Amazon under $100. Wire the A/C circuit through the sensor and the hair dryer circuit to it so it can't run with AC unit on. Could also wire up to prevent an appliance in the kitchen from running. May not be too practical if AC is running a lot and voltage is low tho.
Not to hijack this, but this is an interesting concept since you could wire the microwave thru the sensor with the A/C powered thru the NC relay contacts so that when the micorwave is powered on it would cut off the A/C. Do I have that right? Also, why do you say "May not be too practical if AC is running a lot and voltage is low"?
Something like that would solve my single issue of having to be careful about running the microwave when the A/C is on and they are on separate breakers with on other loads but them on each breaker.

I have the CR Magnetics current sensing relay I installed in our TT and I use it to shut off the 1500 watts of built-in electric heating I installed when anything is plugged in that would make the load go over 30 amps. The relay works great. Can plug in the hair dryer, MW or any other high load, and the heaters are automatically disconnected and go back on when the loads are unplugged. It's actually pretty cool how well it works...
I was thinking if the voltage got low at their CG and the AC amps went up, there wouldn't be much left to run anything else on the 30 amp service. The 30 amp breaker doesn't care what the voltage is, and will trip when it gets over 30 amps for long enough (it has an inverse time-current characteristic).
