Frequently Asked Questions
- What if I’m not satisfied with my truck topper through cab protector?
We offer a 30-day money-back guarantee. If you're not satisfied, simply contact customer service and return the product.
- Does the truck topper through cab protector allow for movement between the truck and camper?
Yes, the accordion-style folds are designed to flex, allowing for some movement and vibration without breaking the seal.
- Will one of these work on both sliding windows on truck & cap? I don't want to remove either sliding window.
In order for the boot to attach to the vehicle there must be some sort of thin wall or flange. Keeping the slider window will cover any flange or thin wall. In short you will not be able to use any or the boots if you keep the sliding windows in place as there will be no mechanical method to install the boot.
