to the guy I saw on the 101 with the Ford 350 SD...

I might have tried to wave him down as he sped by and gave him a quick look behind you yell. Probably would not have worked anyway. People like that are in their own mind set and it doesn't include commonsense. I tow triples in CA, boat behind my fifth wheel, and I also installed a rear camera on my fifth wheel so I can see my boat. I always travel the speed limit as I know the CHP keeps an eye out for the unusual. No hurry, I'm retired!
