Pack like you'll need it in a hurry
Use same-size boxes so they stack square, label two sides of every box, and leave an aisle down the middle of the unit. The five minutes it costs you at move-in saves an hour the first time you come back for one thing.
Keep it off the floor
Pallets or 2x4s under your bottom layer keep air moving and protect against the rare spill or blown-in rain. Furniture goes on end where you can — a sofa on its side takes half the footprint.
Texas heat rules
Candles, vinyl records, some electronics and anything wax-based don't love a metal building in August. Store those at home, or ask us which units run coolest.
Prepping an RV or boat for storage
Drain the water lines, pull the battery or put it on a tender, top off the fuel with stabilizer, and cover the tires. Come by every few weeks to run the engine and you'll avoid the spring surprise.
What not to store — ever
Gasoline, propane bottles, paint thinner, fertilizer, fireworks, food, or anything alive. It's a fire and pest issue and it's in your lease for a reason.
Buying the right size the first time
Most folks under-buy by one size. If you're between two, take the bigger one — the $20 difference is cheaper than moving everything twice.
