What's laughable about rollaways is when they get past a certain size won't roll. You could tow it but the casters better be set up right.
I just bought two 42" lower boxes and the first thing I did was remove the casters and install adjustable legs to level them. Actually they don't have drawer locks which I don't like but I also fear the thought of an earthquake just big enough to open some drawers. Wouldn't take that many before the whole enchilada is laying face down. So I tilt them back just a tad.
The old slide guides were never a problem but the newer roller bearing guides are pretty easy to open. One box has thumb operated spring locks. Another has a little bit of a detent. Yeah, I have that many lower boxes, about 7 of them. Not all 42", just 4.
