Was looking around on Summit Racing today and found this
http://www.summitracing.com/parts/SUM-9 ... mage=largeThey have several types of them, and they look to be very similar to the stock one to point that you can just unplug all the wires from your stock one and replace it with one of these. I like that this uses the blade type fuses as well, I think they're more durable than the glass ones. And, it comes with the plastic cover that none of us can ever find for our stock ones. They have 10, 8, 6 and 4 circuit ones. I don't remember now how many circuits you need for a LUV, but I suppose you could just get 2 of them, they are cheap enough. They only go to 15 amps per circuit; but I think for larger loads you should use a relay and inline fuse anyway.
