Yeah, the author implies (intentionally or not) that had the TB been secured with chains, instead, that the CHP would've wished the driver a good day & a safe trip.
Technically, it's a double-tow, which CA allows - as does IL (although I've never, ever seen it in this state except for commercial trucks).
If you count the tow vehicle, you can call it a 'triple', but to me, a vehicle doesn't tow 'itself', so...
@DocBrown -- not looking to stalk you online, but curious as to the RV sites you deem interesting? I know you've been trailering / RV'ing for a while now; I'm still a 'year one' guy.
