When it comes to Packing your storage unit there are a few important things to know to make the process easier during the move and after the moving of your items.
First things first get as many people as you can to help you. "Many hands make light work." You might get some friends or family that starts pulling stuff like the image on this page, but if you can put up with that and have a little patience it will make your overall job a lot easier.
After you get some friends and family to help you, Make sure to have plenty of packing materials such as paper, bubble wrap, blankets, newspapers... whatever you can find that will keep your items safe and protected during the move. As you put things in boxes, grab a sharpie and label the boxes. This will help save a lot of time later.
Once you'r items are all packed up in the transport vehicle, brainstorm a game plan for when you arrive at the storage facility. You may be a little limited on space in the new unit. Think of what Items will fit close together to maximize your space. Also The heavier and bulkier items usually store better on the floor of the unit. As you start packing your unit, try to make a pathway to the rear of the unit. An Isle will help if you ever need one item in the back of your unit so you don't have to pull everything out to get to it. Awkward shaped items are better stored towards the top of the unit towards the ceiling.
Finally secure your storage unit with a tuff lock. I would recommend a disc lock, they're nice because the bar isn't accessible to bolt cutters.
