I too am considering changing my faucet to a high rise model.
I just need to make sure it will accept the threaded garden hose adapter to allow those outside showers when needed. The trailer didn't have one but I will adapt and overcome.
As well if your trailer does not have 120v plug on the outside you may be able to put a "multi plug" adapter where your
fridge plugs in and have access to power outside. I am sure this is old news to you trailering vets.
