Walmart tents offer a cost-effective way to take your family camping. A low-profile tent may be a good option for someone with a disability. They are more maneuverable and will let you walk around the tent. They offer a lot of space for you and your family. With a square foot of floor space, you can easily fit an inflatable mattress, a sleeping bag, or all your personal gear. You will need to be able to reach your feet if you want to put on clothes inside of your tent. In general, 25-30 feet is enough.
