Car camping with a 40-pound dog was not something I felt confident my setup could handle. When I agreed to foster Rex, I was fairly convinced that he would not fit comfortably into the life I had already built inside my Toyota 4Runner.
Riven traveled with me for years at around 25 pounds. Rex brought a larger body, longer legs, and a completely different way of moving through a small space. The 4Runner already held my bed, kitchen, food, water, work equipment, and everything else I use while living on the road.
Adding another 15 pounds of dog felt like a much bigger difference once I pictured all four legs stretched across the back.
A One-Week Foster Plan
My original plan was to foster Rex for about a week. He had recently been neutered, so I booked a hotel to give him a clean, controlled place to begin healing. That also gave us time to get acquainted before testing whether he could live comfortably in my car camping setup.
His recovery moved faster than I expected. By the third day, his incision looked good and he had enough energy to need more mental stimulation than a hotel room could provide. He still needed limited activity and careful monitoring, but remaining inside all day was not helping either of us.
The forest offered a reasonable middle ground.
Moving His Recovery Into the Forest
We kept the walks short and slow once we reached the forest. Rex could sniff around, take in a new environment, and use his mind without turning the outing into strenuous exercise. I continued watching his incision, keeping him clean, and limiting how much he did while his body healed.
Monsoon season helped control the pace.
Thunder did not frighten Rex, but he had no interest in standing outside during a storm. When the rain arrived, he climbed into the 4Runner, settled onto my bed, and rested until the weather improved.
Those storms gave me the first honest look at what sharing the vehicle with a dog his size would involve. Imagining where a dog might sleep is easy. Spending hours together inside a small rig while rain limits the rest of camp gives you a much clearer answer.
The Bed Became Rex’s Space
Rex loves to nap on my bed, which became one of the reasons the setup worked so well.
While he rested, I still had access to the floor, storage, and the back of the 4Runner. I could organize supplies, reach what I needed, and make meals without asking him to move every few minutes. Keeping him on the bed also helped separate him from food preparation, hot cookware, and the areas where I needed to work.
He had a comfortable place to settle without stopping the rest of the setup from functioning.
The remaining floor space gave him another option when he wanted to stretch out or stay cooler. He could move between the bed and floor depending on the weather, what I was doing, and where he felt most comfortable.
This is where the years spent refining my layout began to pay off.
My Shower Awning Adds the Missing Room
I cannot stand or change clothes inside the 4Runner. My covered shower awning handles the parts of daily life that require more height and privacy.
The awning extends the usable setup beyond the vehicle without requiring a larger rig. I can change clothes, stand up, and handle other camp routines under cover while Rex remains dry and comfortable inside.
That division of space became especially helpful during monsoon weather. The 4Runner did not need to serve every purpose at the same time. Rex could nap on the bed while I used the awning, then I could return to the rear kitchen and prepare a meal without disturbing him.
The vehicle and awning work together as one system. The 4Runner provides the bed, shelter, storage, and kitchen. The awning supplies the standing room the interior cannot.
A Backpacker’s Mansion Put to the Test
For years, I have treated my 4Runner like a backpacker’s mansion. The space is compact, but nearly everything inside has a purpose and a designated place.
A larger dog exposes wasted space quickly. Loose bags block the floor, poorly placed gear interferes with movement, and anything without a home eventually lands where the dog needs to rest. My storage systems already kept those areas open, so Rex could join the setup without forcing me to unload half the vehicle every night.
By the end of that first forest stay, Rex’s size was no longer the question I kept asking. He had already found his rhythm inside the 4Runner. He napped while I worked, watched the storms from the bed, and moved through camp without requiring me to rebuild the life I had spent years refining.
I expected that week to show me all the reasons a 40-pound dog could not live comfortably in my setup. Instead, it showed me that the setup had room for more than I thought.
