This project was built and designed by Mark from Gunflint Designs. It’s a custom travel kennel built to keep dogs safe, comfortable, and secure during truck rides.
When growing families add new pets, travel logistics can get tricky. Mark shows how a well-built dog crate can solve space constraints without the need for a bigger vehicle—and turn DIY effort into a lasting solution.

Addressing Space Challenges in the Truck
With two dogs and expanding family needs, Mark’s truck backseat quickly became overcrowded. Instead of upgrading to a larger vehicle, he took the smarter route by building a custom dog box designed for the truck bed.
The goal was to create a solid, insulated space where both dogs could ride comfortably and safely. A project like this not only protects pets but also frees up critical interior space for passengers and gear.
Careful Planning and Measurement
The first phase of the project involved detailed planning and measurements. Mark measured the truck bed, factoring in space for future flexibility and the comfort of the dogs.
He then outlined the crate’s footprint on the shop floor, using tape or chalk to visualize how the dogs would fit inside. This step helped him adjust dimensions early and avoid mistakes once construction began.
Selecting the Right Materials
For durability and insulation, Mark chose sturdy plywood and added interior sheeting. The basic structure resembled framed wall construction, similar to building a small house.
The walls were layered to provide both strength and protection from cold surfaces. Insulating the box was critical to keeping body heat from escaping during cooler trips, making the ride more comfortable for the dogs.
Constructing the Dog Box
With a plan in place, construction started by assembling the base and wall sections. Mark cut the plywood to size and framed out the box using simple but strong methods to ensure rigidity.
There were a few changes along the way as real-world conditions highlighted the need for tweaks in the design. At one point, Mark disassembled part of the build to make improvements, a reminder that flexibility is a vital skill in any DIY project.
Designing for Safety and Ease of Use
Throughout the build, safety remained a top priority. The structure was built to resist movement, shifting, or collapse even when loaded into and out of the truck.
The interior was left open enough to allow easy loading and unloading of the dogs. Additionally, Mark positioned anchor points so the entire box could be secured to the truck bed, ensuring it stayed put even during rough drives.
Protecting the Build with Durable Finishes
To shield the crate from the elements, Mark applied a heavy-duty, waterproofing paint. This sealant filled small gaps, added a protective coat against moisture, and helped extend the box’s lifespan.
Choosing a tough finish was crucial for a project destined for outdoor exposure. Truck beds see all kinds of weather, and the finish needed to resist water, dirt, and abrasions over time.
Real-World Testing and Adjustments
Once the box was finished and installed, it was time for a real-world test. The dogs quickly took to their new space, hopping in eagerly for their next adventure.
The anchor points held the box securely in place even during travel. Mark’s dogs were safe, comfortable, and separated from cargo and gear, making for safer trips overall.
Planning Ahead for Future Needs
While the crate was designed for two dogs, Mark thoughtfully left enough space to accommodate a third if needed. He also considered adding a removable partition to separate the dogs if necessary.
This kind of forward thinking shows how DIY projects can grow with a family’s changing needs. Building with flexibility in mind means the crate will stay useful for years to come.
A Practical, Durable Travel Solution
Mark’s project demonstrates how custom solutions can outperform store-bought alternatives. A little time in the shop produced a safer, warmer, and more comfortable space for his dogs—without the need for a costly vehicle upgrade.
The travel kennel turned what could have been a major headache into a simple, durable solution. Projects like this show the power of woodworking skills applied to everyday problems.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
Projects like this truck bed dog crate really showcase how custom woodworking can solve specific family needs better than any store-bought solution. The combination of proper planning, solid construction, and weather-resistant finishes creates something that’ll last for years of adventures.
The insulation aspect is particularly smart here. Dogs can overheat quickly in summer and get cold fast in winter, so that layered wall construction with interior sheeting makes a huge difference in comfort. When you’re building something that’ll live in a truck bed, moisture protection becomes critical too – that heavy-duty waterproofing paint will pay dividends down the road.
From a safety standpoint, those anchor points are essential. A loose box in a truck bed becomes a dangerous projectile during sudden stops or accidents. Taking time to properly secure the crate to the bed shows good thinking about real-world use. The dogs stay safe, and so does everyone else on the road.
Building with future flexibility in mind is always wise. That extra space for a potential third dog or the option to add partitions later means this crate can adapt as the family’s needs change. It’s the kind of forward-thinking approach that turns a good project into a great long-term investment.
