Built to Explore
Four Wheel Campers have been helping adventurers explore farther since 1972. Lightweight, durable, and purpose-built for life off the pavement, these campers are designed to go where traditional RVs can't.
Whether you're chasing remote campsites, weekend getaways, or full-time travel, MULE Expedition Outfitters can help you design the perfect Four Wheel Camper setup for your truck and your style of adventure.
Pop-up campers offer a unique balance of comfort, capability, and practicality. Their lightweight construction and low-profile design reduce strain on your truck, improve drivability, and open the door to destinations traditional RVs can't reach. Whether you're exploring forest service roads or heading out on a weekend getaway, a pop-up camper lets you travel farther with confidence.
For more than 50 years, Four Wheel Campers has built campers designed specifically for off-road travel. Their philosophy is simple: keep weight low, prioritize durability, and create products that stand the test of time. The result is a camper trusted by overlanders, weekend adventurers, and travelers who value reliability wherever the road leads.
No two adventures are the same, and your camper shouldn't be either. Choose from a wide range of floorplans, power systems, appliances, storage options, and accessories to create a setup tailored to your truck and how you travel. Whether you're planning simple weekend escapes or extended off-grid expeditions, we'll help bring your vision to life.
Getting into a Four Wheel Camper is simpler than you might think. Reserve your camper with a deposit and explore financing options designed to fit your budget. Our team will guide you through every step—from selecting the right model to installation—so you can focus on planning your next adventure.

Yes! MULE offers a wide range of upgrades for both your Four Wheel Camper and your truck. We carry popular camper accessories including awnings, upgraded mattresses, power system upgrades, mounting solutions, and more. As a full-service vehicle outfitter, we can also help prepare your truck with suspension upgrades, airbags, wheels and tires, braking upgrades, and other modifications to safely handle the added weight of a slide-in camper. Many lightweight Project M campers require little to no suspension modifications, and our team can help determine what, if anything, your truck needs.
Our showrooms typically feature 3–5+ Four Wheel Campers on display at any given time. This provides you the opportunity to explore different layouts, features, and options in person.

No, Mule is not a licensing agency. At time of installation you will be given an official “Mfg’s Statement of Origin” (MSO) and a copy of the paid invoice from MULE to show that you already paid the sales tax at point of sale, 8.8% currently.

WA has an exemption for out of state buyers to not pay WA sales tax on a camper purchased in WA, and to be taken back out of state. If your drivers license is from another state and you are taking the camper back to your home state, you don’t have to pay WA sales tax at point of sale: https://app.leg.wa.gov/RCW/default.aspx?cite=82.08.0264
No, a topper like Project M does not meet the definition of an RV in the state of WA so no license is required. However, since Project M toppers do not meet the definition of an RV or camper, there is no out of state tax exemptions for Project M.
