I am looking to run a "hot" wire from my 2005 Toyota Tacoma Extended Cab 4x4 truck (non-TRD, no Tow Pkg) for charging my truck camper's battery. I know I need to run an isolator, but wanted to see if anyone has some specific instructions/diagrams/pics. I have basic appliances in the camper and will not need a high amp isolator. The biggest concern is having enough power to run the refrig while on the road. I'll change it over to gas when parked so it doesn't run down the aux. battery. Thanks.
