My take on the differences is its mostly cosmetic - but when I 'm paying this much for a box and expect it to last the next 30 years for me that mattered.
No spot welds on the drawer fronts, Extreme's welds are on the side and there are gussets on the inside.
The drawer fronts are straight down on the Extreme - a little bevel out at the bottom from what I can tell from pictures on the Montezuma.
The gauge of the drawer fronts on the top box is heavier on the Extreme than the Montezuma.
The drawer pulls are solid aluminum on the Extreme vs an extension of the drawer front wrapped in aluminum on the Montezuma
A little higher gloss black on the Extreme.
From my research and talking with vendors - Both boxes are built in China - probably at the same plant and just built for different companies in the US.
Also found out the RXE Extreme is the same box as the Menards box - just a different color - black or blue vs green for the Menards boxes. it's not the box I got - but I did consider it - it's a good bit less expensive but a little less bling and lighter gauge metal in the drawers and sides and less drawers on top in exchange for the pull out work surface.
They are both great boxes I am sure - just spent another $160 to get the Extreme vs the same size combo from Montezuma for the cosmetic differences.
I got the box today, and pushing it off the pallet a little to mount the wheels worked great! No need to flip it on it's back. I did end up having a friend help me put the top box on instead of using the Cherry picker - let me just say though - Don't try this by hand without a few guys to help if your back isn't in good shape, its very heavy and a long lift. I used the plastic packing to cover the lower box sides at the top before we set it on there to make sure we didn't scratch anything up - then just lifted one end up and pulled that side's plastic out, then the same on the other side.
I'll post some pictures tomorrow - spent an hour or so moving some tools over from my old box to the new one tonight - i'm going to have to get some wrench holders to get it organized - my other ones are in the old box and adhesive back stuck to the drawer bottoms. Going to try to get some that are magnetic that will hold through the drawer liners.
Overall, very happy with the box and the service from Tool-Xpress - it's a nice piece and a good price.
