Open car trailer vs enclosed

Ok I’ll do the open trailer. Only other good thing about a closed trailer is I could move my cars and pack up some of my **** in the garage/spare room to move to the new house.

the alternator in my purple car died this morning going to get donuts so I’m gonna have to find a new alternator for it.
I was shopping for an enclosed trailer for my racecar, and also to move three households of stuff for my family, from california to Arizona. Very disappointed by the premium placed on West coast trailers, compared to back east. Roughly 75-100% more.
My friend found a box truck with a rebuilt diesel with a lift gate, that was being sold cheap (less than half what a 24 ft trailer was getting)
California has literally outlawed older diesel work trucks, every two years, two more years of trucks become un-licensable. Since we could title it in Arizona we bought it, it has easily paid for itself already. It did need tires (I'm told, I wasn't there) that cost about a third of what we paid for the truck.
(Oh, and it's perfectly capable of towing my racecar, or any other car I own, on my open trailer.)
Every couple years there is a glut of perfectly usable california diesel worktrucks available.....if you can title them somewhere else.
Edit: I could probably carry my Opel in the box..... if I could find suitable ramps, long enough and stout enough....
