Running wires from battery compartment to inside

What is involved in running wires from battery compartment to the inside of the motor home. I have run lots of wire in normal home but find the MH a bit intimidating as I don't what the floor/wall are made of or what where? I could just pay some one but seems over all a simple task

I have run wires through the floor into storage bins and open areas. My floor is made up of a metal framework with a sandwich of flooring - plywood on top, then foam board with a thin metal sheet on the bottom. A hole saw or drill bit readily goes through it. The only problem I have is determining where the metal framework is located. I use a small diameter drill bit to make a couple investigations to see if a spot is clear of the framework. Go for it, you'll not mess up anything you can't readily fix.

If you don't have a high-quality stud-finder, rent one to help locate metal bracing, wiring, etc.
Depending on the amperage required for your new 12V feed line, you might look around to find an existing one capable of carrying the needed amperage. For example, I have a 12V breaker panel in my bathroom if I have the need for adding something new.

Another option is to run the wires encased in a hose or sturdy plastic tubing and secure it to the underside of the coach along with other lines. Then you can bring them up through the rubber ports where the other wiring comes through. Quick easy and no drill.

Most folks add unjacked wire whenever adding something to a camper or motorhome. It ends up looking like spagetti, with wires run over and through sharp metal corners & edges. Do yourself a favor and buy some tinned marine jacketed 12v wire. The jacket prevents chaffing, the tin prevents corrosion and the two or three wires are together in a proper professional run. Any marine store carries this type of wire, above is just one example.
