Running RV wiring

Question

I've recently purchased a 2007 Winnebago Sightseer, model 33T. I'm interested in running some new wiring for cameras and televisions, and possibly adding 110V outlets. I've got wiring diagrams from Winnebago, which include information such as "Route cable down left A pillar". What it doesn't contain is instructions for gaining access to wiring channels such as the left A pillar. I'm sure this varies with manufacturers and models, but any tips would be appreciated, for how to get to the existing wiring and how to add new wires. Is there a service manual available? Winnebago didn't seem to offer one, but perhaps someone else has produced one. Thanks!

Just like a home, RVs are pre-wired, before cabinets, trim, etc are installed.

It -might- be possible to "fish" wires through existing openings, but.... don't count on it. The use of laminated sections often means the wires go through (cured) foam.

It often takes a great deal of thinking, and flexibility, to wires near where you would like them.

What you need is available in most large hardware and home improvement stores. The name varies, but your store manager can point you too the correct aisle.

names include
surface-mount channel
surface channels
surface raceway

The channel in plastic or metal is screwed to the wall, wiring added inside and the top cover snaps shut.

place the channel in corners where it will be unobtrusive. Remember to buy corners for changing direction, and surface mount boxes for switches and outlets and the wire and switches.

You can also run the raceway INSIDE cabinets and dinette storage and mount only the plug and switch boxes on the outside surface.

You may have to remove several other trim pieces before you can get the A pillar trim loose. While you have the cover off the A pillar, be sure nothing in there can vibrate and rattle or you may have to pull the cover again.  I've used pieces of an old pool noodle as padding to stop the wiring rattle in the A pillar. Wiring for rear camera's can be run down inside the rear cap, along the frame rails and back up into the driver's area.  Be sure to protect the wiring from heat and vibration and tie wrap securely.Fred

Thanks for the suggestions! In some places, I can't even see how the paneling or trim would be removed by a person hoping to replace it. Running camera wires at the bottom is a good idea.

There must be a way that service technicians can get to the existing wires, but as in a stationary house, it might involve replacing wall sections.
