How to make use of space where generator was?

I went to a welder and for what he charged to weld it and paint it I could not have bought a piece of flimsy plastic for that price. If you are looking look for a small welding shop like a one person operation. The big ones won't give you the time of day for a small project like this.

Here are some pictures of mine and some other mods 19G mods

FYI I still have the old battery box there, I need to find a tool box that fits it as it is a perfect location for tools or oil or even a small can of gas.
