Adding Outside Lighing

I'm in the process of adding LED Outside Lighting to my Toy Hauler. Two front work lights 7 watts each. Two side docking lights 7 watts each. Two under carriage flood work lights on separate circuits 10 watts each and two rear ramp lights at 18 watts each.

I am installing 5 rocker switches inside the trailer at the information panel where all the other switches are located.

I am going to install a 6 circuit fuse panel at the location of the switches, so each light circuit will have it's on fuse.

I WAS planning on running power and ground from the front storage compartment where my Solar buss bars located to the new fuse panel in the information panel.

This would be about a 30 foot run. I do happen to have some 8ga wire that would work BUT When looking inside the information panel I could tap into a number of DC power sources like the outside LED lighting 15A circuit.

Adding all the new and old outside lighting together I would still be way under 15 amps even if they were all on at the same time which is very unlikely.

#1 tap into available DC source to Aux fuse panel?

#2 run separate power/ground wire from front buss bar location to Aux fuse panel?

Any thoughts?
