Hi Guys, first post so go easy please 
I've been searching all day and have found numerous posts about the KRL boxes but haven't seemed to find exactly what I'm looking for.
Pretty simply put, what are the differences from the KRL1001 and the KRL7022?
I guess another question would be if you could buy either one at about the same price and condition which would you buy? Or which is the better deal/box? I'm looking at two different used (private party) boxes, both seem to be in good to great condition and within $200-$300 of each other with the KRL1001 being cheaper.
Thanks a lot for your help!

The SO site doesn't list the KRL1001, when I do a search it goes to the KRL1022 so I'm guessing the KRL1022 has replaced the KRL1001, but not certain. Based on those comparisons it looks like only real difference is height of the KRL1022 and of course cubic inches.
