HF roller cabinet longevity

I have a mix of boxes (Mac, Snap On, Craftsman, HF, and others). My Mac boxes are by far my favorite, and the Craftsman are by far my least favorite.

I use a HF as my welding cart. I made a bottle rack on one side and have my welders and plasma on top. The drawers are loaded with wire spools, clamps, grinders, disc, and everything else. It is rediculously overloaded and rolled all over the place. No problems.
