Ads On Fire Engines?

Nothing wrong with ads. If it can help fund equipment or other improvements then why not.

I think it would be really difficult for a company to provide any type of specific revenue reports that were created from someone seeing an ad somewhere. They would literally have to ask every customer why they were there which would be unrealistic. The only other option would be to have a “promo code” on the trucks that people can use which would link sales directly to that. That would also help the company track the viability of their ads on the fire apparatus.
