Sometimes your house is just too small. You have all the essentials covered: living room, kitchen, bedrooms, bathrooms. But you don’t have extra space for your man cave.

For most people constructing an addition onto the house is just too expensive, especially for a luxury room. If you were having another baby, maybe things would be different. But it’s hard to justify shelling out the cost per square foot for a place to watch your movies at an unreasonably high volume.

So what is a man to do? The answer might be a mobile man cave. You won’t take up room in the house, and you’ll have your space. Here are three vehicles for your mobile man cave setup.

RV

Recreational vehicles come in a wide array of shapes and sizes. Campers, fifth wheels, pop-up trailers, and more can satisfy your man cave needs. Most RVs will work in a man cave setup, but the teardrop camper is out. You can only go so little with a small man cave.

Tables, couches, refridgerators, and televisions are all common fixtures in RVs. You have a premade layout that takes care of the big pieces and lets you focus on the details to make your perfect space.

And like some backyard man cave structures, you can even have a bathroom. That comes in handy when your friends come over, and you wife doesn’t want them coming in and out of the house all evening. Or you can keep working on a hobby for hours on end because you won’t get distracted when you go in the house for a bathroom break.

Boat

Unless you live on a lake, you probably won’t keep your boat in the backyard. But a boat can be a man cave. What could be better than catching your dinner and enjoying it in your man cave without changing locations?

Even when you’re docked, you can have a little place all to yourself. Sure, a boat can be cramped if you stay for a long time. But if it’s what you have, make it your own!

Van

You’ve probably seen YouTube videos of people living the “van life.” They make a tiny studio apartment out of a van. Then, they take it on the road to see the country. Some even have tiny showers!

Honestly, most of those van lifers look like they’re on the verge of an emotional breakdown. They put on a brave face and tell themselves they like their lifestyle. And maybe they do, but you can imagine it gets a little too cozy sometimes. And bathing at gyms and truck stops all the time sounds like a drag.

But a van could be a perfect man cave. If you want to be alone or with just a friend of two in your man cave, a van has just the right amount of room. Plus, you can take it to a boys night out! This arrangement also works with a box truck or any other four-wheeled vehicle you want to transform into your man cave.
