I use a Whelen PCC8R for things that need switching, and a pair of basic blue-sea fuse blocks for things that don't. Things that stay hot when ignition is off and have their own power switch (spot light, HID relays, external speaker, fridge, ham radio, etc) are on these fuse blocks. There's one in the engine bay for front related things, and one in the back for the stuff inside the truck.
The Whelen is used to control the rest of the additional lights in the vehicle, including the Rigid LED lights on the back bumper. It gave me a small easy to operate switch panel that I mounted next to the transfer case lever, and kept the wiring pretty neat in the back, with all the relays built-in. It's something to consider, your setup might not require something as fancy.
