Yes. It will go with me to Arizona first to be used in my 5th wheel. I did buy a President Washington radio the other day. Just waiting for it to be shipped to me.
Can run 12V radio straight off house batteries given inverter has some capacity.
So, unless you’re going to run wattage higher than an export, you’re already set. Amp draw for a KL503HD @ 150W limit would need to be figured (fuse rating) to play on SSB with a portable exterior antenna (tripod, extending mast, in a tree, etc). I’d use a 100’ coax run as a baseline.
A travel trailer is a mobile. Wire to POS (fused) and can run NEG to BATT,
or, to trailer frame ground (my choice) where BATT also ties (same as with my pickup).
Granted that this can limit location of radio rig. It suits mine as both inverter and lounge area are in the bow.
If you were going straight to the Utility park power 15A receptacle then need to think about how to run. Marine-style flush-mount receptacle would seem best.
Maybe you know an electrician.
— Astron lasts forever (seriously heavy).
— Mega-Watt inexpensive and robust by report.
While at home (now) would be a good time to start the “interfering RF” search. LED, and other devices factory/installed (circuit-by-circuit) versus being on the road and away from home & shop.
RV electric as you know is kinda weird already. I’d want to run anything which is thus powered while at home. All appliances, etc.
It’d also be the right time for a concealed coax run to a location for vehicle exit.
