They're probably going to at least one regional at $5,000 each year, probably spending at least a couple of thousand on their robot and another couple of thousand on travel, shirts, buttons, etc, for a total of around $10,000 per year.

If a trailer lasts 10 years, I don't consider the cost of a trailer at $4000/10 years = $400/year plus $100/year in maintenance for a total of $500/year to be unreasonable for having the convenience of your own trailer. It's much nicer if the inside is customized to hold all your paraphernalia rather than just tossed into a U-haul.
