Nope to both.
I installed a 12 volt outlet (female cigarette lighter plug) just under the counter, up above the 12 volt fuse box. This allowed me to very easily use a new connection from the fuse box.
1. Disconnect shore power and battery.
2. Remove fuse box from wall
3. Attach ground, and hot wire to new fuse location.
4. Add 15 AMP fuse
5. Run wires to new 12 volt outlet. Had to drill hole to mount outlet, and one hole in shelf to pass wires through from outlet to fuse box.
We primarily use the outlet to charge stuff - phones, computers, etc.
I'd show photos, but someone stole my camera about a month ago.
I'm waiting on the new Pentax K7 to come out in July
