Not all 6" aluminum I beams are the same on the trailers. Look at the thickness at the webbing, some are twice as thick and much stronger. I would want all stainless hardware and 316 grade stainless not cheep 304. Also watch out on the type of aluminum grade they are made from. There are some made from better quality (grade) aluminum than others. I would get "acu-lub" hubs. They add grease from the inner bearings to the outer and lube better than the buddy style. Torsion axles will last three times as long vs leaf springs and get you closer to the ground for easier unloading. There are many different brands that are good but I would look for the way they are built due to some companies sell a economy model and a heavy duty that look about the same but one will be better built and more money a course.
