So we recently purchased a new 2016 Cruiser MPG 2400BH trailer...... And the fun begins, first day home and the batteries are so low that the awning will barely move. Figuring that the dealership forg...

Wow... 4 AWG!!! you certainly shouldn't get much loss with that. I certainly can't fault you for under doing things.... I considered going with 8 or 10 but so far the 12AWG seems to be doing fine for me. I am running about 14ft from the panels to the controller.
I used 4 AWG throughout since I have a fairly sophisticated distribution panel and it was easier/more efficient for me to buy a 100' roll of 4 AWG welding cable, terminate it all with the same lugs, and have low loss of harvest (I'm what some call a "ma counter"). I have one double run of 1/0, to connect a separate bank of 2 X 6V's, run of 6', to the distribution panel. ATM, all my batteries are inside the trailer. I don't plan to change that, it works too well for weight distribution and security. I know what I have is unique and I'm not advocating anyone do the same. I just hope others know how wire size can influence the efficiency of their 12V charging systems. Too often, what is in place from the factory is not efficient or desirable to the RV hobbiest.
Btw, here's a capable meter for measuring amperage in the range for most RV systems: Tenma meter
