Very unique situation - dot rules?

Hey gang - I am in a pretty unique situation and could use your guidance.

I have a 2017 Western Star that I am converting to look like Optimus Prime from the movie Transformers. It is not being used for a business and will not be used in hauling of any kind. I will never trailer anything, and don't use it to move people or goods. It is a truck that I own (or make payments on). I will be taking it to trade shows and comic conventions for fans to enjoy. No commercial or monetary gain of any kind. And if I do, any proceeds will go right to charity.

This is an untapped area when it comes to the DOT rules and regulations. Yes it is a commercial truck that's over 10,000 lbs, but it is not being used in interstate commerce. It is truly just like a personal vehicle.

So what are the rules here? For one, I don't THINK I need a DOT number. Do I? Two, what about things like fuel stickers for any states I drive through? Do I need them?

I do intend to stop at weigh stations just in case. But it's really a gray area that I can't find much information on. Any guidance would be greatly appreciated!

And please... spare the unsolitced comments about what I am doing or how stupid you might think I am for doing it. I just want to make sure I am following the rules of the road. Thanks!

 

Thanks guys. The old Optimus was a Pete I believe. The newest model is the western star 5700.

x1Heavy - I figured stopping at the scales was a requirement for any big rig. Plus I felt it would be easier to stop their and explain my situation (if asked) vs passing the scale and trying to explain it to a pissed off officer who is wondering why I just blew by the scales.
