M109 fuel tank/spare tire dimensions

[Danger Ranger]

OK, so just wondering about the spare tire carrier and/or fuel tank on m109s. Anyone have the dimensions (height, width, depth) of a tank. If not, how about spare tire rack...
Just curious about mounting a generator there after seeing all those m109 builds.

DR - I had actually wanted to intall a Gen Set 4 kw Emerald unit I had as a slide in unit. Removing the tool box and making a slide in unit and then using the OEM door as a final closure unit so no one knew what was behind it.

Meaning - open the door - slide the gen out - so all was incognito

The area for the spare tire is a 42" circle. The fuel tank is about 15" tall. That is about all I can do without a truck and a tape measure next to me.

OK, duh...

42" tire means the area there should be at least 42" deep, 42" wide, and the tank height of 15" means 15" tall.
Thanks for the quick input guys!
