Our coach had a two-handle, low spout Phoenix-Brand faucet. It started to lead at the valve washers and stem seals but worse at the O-Rig where the spout swiveled. We bought this Phoenix quarter turn high spout faucet on Amazon
Pic doesn't show the attachments, but the point I want to make is that at least in our Jayco, the supply lines attached with plastic "wing nut" couplings, and the faucet itself attached to the bottom of the counter top with plastic "washer/nuts" that again could be worked with fingers. So with reasonable flexibility, dexterity and hand strength, might be able to swap it out without even needing tools.
Be sure as you shop for a faucet that you get one with the same mounting "footprint" or "form factor" that you have now. Many residential faucets are three-hole. They mount at the center and water comes in through the center. The mountings at the ends only hold it in place. Our RV has only the two end holes and they serve as both mountings and water connections.
