The electric fan will give him the control he wants.
Please, need suggestions on material and thickness. I have little experience with aluminium. I do have a good box break to bend the material.

What say you?

The .080 is a fine thickness for your diesel bracket truck, using 3003.
Since 5052 is about double the strength of 3003, with both in half-hard, I would use .050" in the 5052.

Remember your radius bends are more generous with the 5052 than with the 3003.
Use 5356 filler with the 5052.
Show your results, please?
