Road train lighting

[tamiya fan]

I have a question, if some one could help. I am building a 2nd flatbed to go with my 1st one. I would on occasion like to run the 2 together with a dolly in between.
So my question is, has any one run the 2 trailers, dolly, with lights for all 3 running off of MFC? This will be 4 tail/brake light, 4 turn signal lights each trailer and then dolly. I know the MFC has it's limits. Just wondering if some one has accomplished this, before I go through all the work to find out it won't work. I don't want to design a circuit if I don't have to. Any answers/Ideas?
