It’s almost as if they didn’t care when assembling. Random assortment of holes taped over and painted. Some missing from assembly and now corroded. (Bottom left/top right) I assume to keep paint out of the hole- instead there’s now bare steel, and the holes are as well- which means water + dissimilar metals and vibration… awesome 80% of the bolts pulled out are corroded where there is metal on metal - which means more parts delayed while ordering replacements
