It just little details like how RCI has welded rings around the bolt holes and that they used a clip style nutsert on the hatch and send extras. That being said I still drop the skid to do an oil change rather than use the hatch. But now that Im looking at them again i do hate that they only offer black powdercoat on the steel. I got an early set before they changed up their design, logo and still offered bare steel.
I had minor alignment issues with bolt holes on my BB. One of the brackets was bent, not sure how or if it was shipped that way or happened in transit. I hated the sunken bolt holes on the BB. They could be a pain in the ass. The low vent holes on the BB collected mud like crazy.
