I'm assuming those are FEMA trailuhs.
So, now they put the kibosh on subs.
When it comes to washing them.
When they were being delivered and set up the subcontracts went 5 or 6 levels deep that I know of, maybe more. That's why each of those cheap boxes cost 70 grand to get on site.
A buddy of mine said that 8 different crews that he knew of came to his place for his trailer. They would bring 5 or 6 guys and just stand around, check one thing, get a signature if possible, and leave.
