The bed of a pickup truck provides you with a large amount of space to carry various products, but you want to be confident in the security of whatever you have in your truck bed. There are a couple of options for enclosing this space that you'll want to consider. One product is a tonneau cover and another is a truck cap. You'll find multiple examples of each product at any automotive accessories retailer, so you can take stock of your options and choose what's best for your vehicle.
