How Do You Seal a Truck Camper Shell?

A truck camper shell is an essential addition to anyone who uses their truck as a primary mode of transportation or recreational vehicle. It helps to protect the cargo from the elements, provides additional storage space, and can even add additional security.

However, it is important that you properly seal your truck camper shell in order to ensure that it lasts for years to come.

Step 1: Inspect for Leaks
The first step in properly sealing your truck camper shell is to inspect it for any potential leaks. Look around the edges of the shell and check for any gaps or holes that could allow water or air to enter. If you find any, use a sealant such as silicone caulk or weather-resistant tape to fill them in.

Step 2: Check All Seals
Once you have inspected and sealed any potential leaks, it is important to check all of the seals on your truck camper shell. This includes both the door seals and window seals. Look for signs of wear and tear, such as cracks or gaps, and replace them if necessary.

Step 3: Apply Sealant
The next step is to apply a sealant along all of the seams of your truck camper shell. This will help ensure that no moisture can penetrate through these areas and cause damage to your cargo or interior of your truck bed. A good sealant will also help reduce air flow which can cause condensation inside the shell during colder months.

Step 4: Test The Shell
Once you have completed all of these steps, it’s time to test out your newly sealed camper shell. Fill up a spray bottle with water and lightly spray down each area where you applied sealant. If no water penetrates through then you have successfully sealed your truck camper shell!


Sealing a truck camper shell is an important step in keeping your cargo safe from the elements while on the road or in storage. It requires a few simple steps such as inspecting for leaks, checking all seals, applying sealant, and testing it out with a spray bottle full of water before use. By following these steps carefully, you can ensure that your truck camper shell will last for many years.
