Cable Chase!

[RobRV]

I have a 1998 DSDP on a Spartan Chassis. I need to Fish a couple of Things through the Frame from Rear to Front. Is There a Chase in place that I can use?
On the subject of running Wires or more properly Cables , what would be the Best way to add to the Battery Bank?
There isn't enough Space in the Compartment and of course the Next Box forward houses the Electric Distribution stuff, as does the Same Box across on the Other side.
That pretty much dictates that I put them forward in the Basement somewhere ahead of the Rear Wheels.
I would like to add 4 More Golf Cart Batteries somehow.
Anyone have any "Ideas"?
Thanks Rob

Just a thought.. You could separate part of the storage underneath the back bed and place them there as you would be right next to the battery bank. I'd totally enclose it and vent it to the exterior just as a precaution.
