Why solenoid?
Why do the majority of RV manufacturers use a latching solenoid for the battery disconnect (storage) as opposed to a mechanical battery disconnect switch? Is there some other function that the sol...

As I said in my comment above, for my truck camper the distance is not an issue due to the location of the battery compartment. Maybe an extra 3 ft of 8 AWG required to install a switch. At least for me, a switch would likely be cheaper. For a large RV with extra wire runs and a higher rated current, the solenoid makes total sense.

The Solenoid, basiclly a big and I mean BIG relay. can easily pass 100 amps or more. The wires that run a great distance to the switch. just a couple amps.
You are asking why they use a fairly low cost remote switch with low cost 20-22 ga wires instead of oh say 50 feet of something between 4ga and 00ga.
Way cheaper. and way better electrically as well. (less voltage loss in the line).
