I had a broken front beam on my previous SOB trailer, Had to repair it myself because I was 600 miles from an RV repair center. The Manufacturer never wanted to hear about my problems though there was a safety recall on the later models.
I looked at the HL design, and the FR design, and I am very pleased with the HL method of cutting the corner beam and the beams that reinforces the front of the pin box.. The FR method depends on many gussets and welds that will fatigue after time.
I also studied the Keystone arched beam and realized that is even worst on the connection and welds.
This front beam has twice the load of the next beam behind the pin box, and it needs to be well reinforced.
Well done HL, you did it right, very pleased with the lack of flex on my trailer, it was the first thing I observed when I hooked it on my truck.
I will not get burned twice.
