Where on this motorcycle do I put the 1,200-1,500 pounds of tools that I carry? I'll keep my 990,000 mile 65 Chevrolet pickup, it's smog exempt, reasonably cheep to maintain, easy to work on, licence fees are cheap, and I can repair almost anything on it with the tools that I carry.
You don't, and you have a good reason to be exempt. No problem here with trucks for legitimate work purposes. If you need your toolbox, you need your toolbox. It's one thing thing for Joe Rancher who needs a truck to pull bales and make a living, it's another thing for a suburban mom to drive her kid to practice in an Excursion because it makes her feel like a supertanker captain. There is a difference.
