Effects of trailer brakes and sway

It's a toy hauler and at the furthest back was my trike. Remember, I drove the same road to the facility with the exact same load with no issues. Also, per Lippert the data plate on the axle is to face rearward. This also will put the brake wire exit holes from the axle going rearward. Heartland has a recall out for axles installed backwards. So yes, they can be put on backwards and upside down.
