JT to the rescue...

I have a small AGM battery on my car trailer. Dont think its much bigger than the AUX battery. I have it charging from the 7way so when I get to a location it has juice. Everything I've pulled up on the trailer has worked. Maybe a thought. Its not large and I wouldn't try dragging something with no wheels but works great for cars tractors and stuff.
