Marine & RV places have fuse blocks.. you run one hot wire to the block, and tap off 3 or more separate lines.
so a search on 'fuse block rv', or head to napa and ask them to show you one. You probably still want a 30 amp inline from your battery to the block. The closer to the bat the main fuse is, the better.
So, the main wire feeds the fuse block, which has several wires going to different items, like fan, lights, etc.... Actually, there are pics here showing the set up, I just don't know where they are...
