This is the recommended footlocker - they're available at Walmart and Target, cost in the range of $20-$30, and can be used to store all of your camping gear during the year.
This is an example of a recommended cot - they're also sold locally at Walmart and Target. Cheaper cots are likely to last for 2 or 3 seasons. More expensive cots will last longer, and wood lasts better than metal in some cases. Older military cots are available at Army Navy stores. The goal is to have your footlocker, shoes, and other items fit under the cot.
