I have a Chinese tank with fuel barrels on the rear. They are very fragile and break off easy. I really like them. That is one of the reasons I bought this tank. It came with a wood case like Ed uses. I would venture to guess he made this one. I have problems as I have a rough time with steps and with this box in front of me it is really hard to do them. Also both hands are full so when I come to a door I can't open it. These boxes are great if you are not an old codger like me. So I tried a cobalt box and it was too short. I tried a Dewalt box that said it was 28 and 1/2 inches long but with all of the reinforcing it ended up 25 inches inside which is too close. I would break the barrels off every time I loaded it. Are the leopards this long. My length is with the turret turned to the back. Are the challengers this long or is this the only one that long?
