Wanted - Cargo trailer for rent for a month

So, just getting a feel for this.
We are moving from San Diego to Bishop. Don't have a lot to move but more than a Moving Van plus all the hassles of that.
Checked into UHaul trailers and one way with a close by drop off is going to run about $120 but can only have for 4 days and my old bones will probably need 5 days and will be 4 trips or so.
So we had a thought, if someone was starting a conversion and needed some cash... I'd rather pay someone $500 for a month and not be limited if I needed to rest for a day.
I need to check with my insurance to see how this would work - "to borrow" a trailer.
Has anyone done this before, is it a good idea, anyone interested in doing something like this?
Add: I can buy a brake controller if needed, want one for a someday thing anyway, have a tow package
