Couldn’t disagree more. Still got the same setup a few years in. As mentioned the sag is minimal (not non-existent), I place a small removable 2×2 near the tailgate so I can hop up top. You’re not building a home up to code, you’re building a practical truck camping solution, and in my extensive experience it is more than fine. You can do thicker plywood, but realize that it will be much heavier and more cumbersome to move.
You may already be aware of something known as the "butt-brush effect," coined by consumer behavior expert Paco Underhill. He discovered that a typical customer, especially women, will avoid going after merchandise in an aisle where they could potentially brush another customer's backside or have their backside brushed. This holds true even if the customer is very interested in a given product. An easy way to avoid this problem is to ensure that your aisle, floor, and displays allow customers to have more than adequate personal space when browsing your products.
DeAnna says that in general, the front left of a retail store is a good location for the checkout counter, like the one above. Shoppers naturally drift to the right when they enter a store and tend to loop around the store, leaving on the left side. So, a checkout at the front left of your store puts it your customers’ natural exit path. Plus, it doesn’t distract them from shopping as they make their way around the store.
I save all my back issues of The Family Handyman magazine and love the projects and repair tips. The trouble is, I’m not always ready to do the project when the issue arrives.
