That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

Hey Dan. The only DC to DC charger that you might be able to get away with mounting in a battery box is the OptiMate Smart Battery Charger item #MA99JR. It has a weatherproof case but it's still restricted to inside use only. An easier and more…

Hi Ben; the difference in the drum size won't make a difference as long as you have a #84 spindle with #L68149 inner and #L44649 outer bearings. The #AKHD-545-35-EZ-K is 10" x 2-1/2" while the #84546UC3-EZ is 10" x 2-1/4" and…
