Tips for Packing A Mobile Moving Unit

Packing The Mobile Attic containers is no different than packing a moving truck, except that it’s easier because it’s ground level, and it’s more important to distribute weight more evenly.

Heavy items and large furniture should be spread out rather than grouped together when possible.

Another tip is to pack important items or things you’ll need to use sooner rather than later toward the front of the container, for quicker and easier access once you’ve arrived at your new location. Things like your mattress, pillows, blankets, bathroom essentials, some clothes, desk necessities, etc should be prioritized.

Finally, keep important documents such as birth certificates, passports, vehicle titles, and medical records with you instead of packing them in The Mobile Attic container, in case of unexpected loss or damage.
