The Uhaul trailers are really heavy, low ground clearance, and you can’t stand up in them. Never mind insulate, have a side door, etc.I have a better idea that I have been throwing around. Rent a trailer from uHaul when you go on your hunt. You can throw all your gear in there and set up cots at night. Then when you are finished with the hunt take it to a car wash and take it back. You wont have to store it, maintenance it or license it.
I paid $2,150 new for my cargo trailer, registration is $25/year. I use mine daily for my carpentry business so it’s a no-brainer, but it’s also handy for moving, storing stuff, etc. You could park the ATV and dirt bike in there and get some garage space back.
I’d never keep one at a storage lot and pay every month just to use for hunting though.
