Umm, yeah, and the builder of the trailer will be there as well. I think there might be enough people there to help noob trailer guy(Carey, Mike, Alan etc.). Remember the trailer only weighs 700 pounds. Lane will be under 2500 or maybe 2700 pounds tops.
When you set a proportional electric brake properly, the brakes just work like normal brakes should. No fuss, no muss. The brakes are self adjusting, so pretty much always adjusted.
When towing the empty trailer, you need to remember to turn the brake controller down as low as possible to prevent locking the wheels.
Trailer towing with brakes is a whole lot better than flat-towing.
