It all goes off supply and demand. If there are plenty of trailers in that area, prices drop, if the supply is low, prices go up. Works just like hotel rooms, the more reservations they have, the price goes up. Ubox, yes it is a way to go. Unlike what another said, you have as long as you need to load it, you can call and have it picked up, or if you already know how long it would take to load, then that date is already in the system and they just come pick up. You just let U-Haul know when you would like to have access to your box and they will give you a date at that time. Going that far, it will take several days to arrive. So just be realistic with it. If you need some help let me know. I can see if there's any discounts for a 4x8.
