Has anybody else dealt with this challenge and has a good plan they can share with me?
You have to keep the rated power draw for the jack in mind when choosing wire size. The overall run length also should play heavily into your decision.
Power trailer jacks typically need a fused, dedicated 30 amp circuit for proper operation. A basic circuit with a 30 amp capacity dictates a minimum wire size of 10AWG.
If your total length is over 20 feet, I would suggest 8AWG to prevent any length-related voltage drop in your jack power cable. Since you only need a single conductor for a jack feed (the jack is self-grounding when you bolt it to the frame), it should be no problem running a single 8AWG wire the entire length of your trailer.
Just be sure to add your 30 amp fuse within 18" of the power source, be it either your battery or positive bus bar. I would also consider the addition of split loom for added wire protection.
