I will be traveling across the US in my 1988 suburban, towing a uhaul trailer. I have electronic devices that I would like to use. Some of these devices have cig. lighter adapters some dont. I was wondering if I could wire my truck with several plug in type ports, their own fuse and seperate battery?
The following are some of the devices:
Cell phone, GPs, CB, Laptop, light, Stereo, Radar Detector.
Any other advice for me to prepare for? l sure would appreciate it.
Thanks
