Exploring Central and South America in a 2004 MCI J4500 Coach
The Dream. To explore Central and South America and embrace a life of freedom and adventure, I’m thrilled to share our incredible journey with you! My name is Jaja, and together with my husband Martin and our beloved dog Yoda, we embarked on a remarkable adventure with our converted bus, affectionately named Jajadabus.
The idea of converting a bus into our home on wheels was born during the recent COVID-19 pandemic. The world was changing rapidly, and so were our lives. We longed for a sense of freedom and the ability to travel and explore without restrictions. Initially, we considered a van or a Skoolie for our travels. However, being six feet tall, Martin would have struggled with the limited headroom in either of those vehicles.

Given that we no longer have a traditional home, comfort was paramount. The 2004 MCI J4500 Coach offered the perfect solution, providing ample space and allowing us to create a true home on wheels. The decision was a no-brainer, despite some people thinking it was a crazy idea. In reality, Jajadabus has become a fully equipped, fully functional, comfortable mobile home.

Finding and Purchasing the Bus
Finding the right bus was a journey in itself. We spent countless hours researching and scouring listings, visiting potential candidates, and envisioning our future home. We looked at several options before settling on the J4500 Coach. The bus, originally designed for long-distance travel, the 45-foot-long coach, had the durability and space we needed. Once we found it, the real work began. Martin spent countless hours researching and planning every conversion aspect, drawing from his construction experience and my background in designing homes and salons.

The Search Process
We initially considered about ten different buses, each with pros and cons. Some were too old and required extensive mechanical work, while others were too expensive. We finally found our MCI J4500 Coach through a private seller who had meticulously maintained it. The bus had been used for charter services and had relatively low mileage for its age. Its robust build and reliable engine were key factors in our decision.
The Conversion Process
We purchased and converted our MCI J4500 Coach during the pandemic, a project that spanned 18 months from start to finish. Martin dedicated over 40 hours a week to the conversion, working tirelessly to make our dream a reality. After completing the major work, the bus was repainted in Mexico, giving it a fresh and stylish look.
Designing Our Home on Wheels
As a professional hairstylist and former salon owner, I wanted to bring a touch of my passion with us. Our kitchen includes an antique table and two salon chairs for cutting hair on the road. The kitchen design, which offers a 360-degree view, was challenging but worth it. We have ample storage with 33 cabinets to keep everything organized and within reach.
Here are 33 of the 36 cabinets. We have three more in the bedroom.


Our bus is designed for comfort and efficiency. It includes a combined washer/dryer (which requires external power), a dishwasher that uses just six liters of water and 500 watts of power, and a 120-volt inverter fridge. The master bedroom features a custom king-sized bed for restful nights, and we have a spacious shower and bidet-equipped toilet to ensure a comfortable experience.

Power and Sustainability
Sustainability was a core principle in our design. Jajadabus is equipped with 12 solar panels and a BlueTech water system with three filters, a 100-gallon fresh water tank, and a 100-gallon black water tank. The bus features air suspension and a unique ZF transmission. Two air conditioning units run on eco mode, consuming only about 380 watts per hour. Inside, we installed twelve lithium-ion batteries beneath the sofa to balance the bus.



Overcoming Challenges
The conversion process was not without its hurdles. We encountered numerous problems and concerns along the way. For instance, our original layout plans had to be adjusted several times due to unforeseen issues. One significant change was the placement of the solar panels and water tanks to optimize weight distribution and functionality. The 360-degree view kitchen was also a design challenge, but the result was worth the effort.
Living On the Road
Since hitting the road, we’ve traveled 53,575 kilometers (33,290 miles) and spent 732 days on the road. Driving a 45-foot bus through the winding, narrow roads of Costa Rica has been challenging. We will cross into Columbia on November 13th and using Overland Embassy for the logistics.
The roads are often in poor condition, requiring careful planning and constant vigilance. Before setting off, we consult truck drivers to determine their routes. The worst roads we encountered were in Mexico, but Costa Rica has had its fair share of difficulties. Despite these challenges, the breathtaking scenery and the freedom to explore at our own pace make it all worthwhile.

Daily Life in Jajadabus
Our daily life in Jajadabus is a blend of adventure and routine. Each morning starts with a peaceful cup of coffee, often enjoyed while watching the sun rise over a new and beautiful landscape. Martin and I take turns navigating the stunning but sometimes treacherous roads. Yoda, our faithful companion, has adapted remarkably well to bus life. He has his own little nook where he can observe the passing scenery or nap during long drives.

One of the joys of our lifestyle is the ability to stop and stay wherever we find beauty or interest. From secluded beaches to bustling towns, our experiences are as varied as the landscapes we traverse. We’ve met fellow travelers, learned from local cultures, and immersed ourselves in the natural wonders of each destination.

Unique Challenges in Costa Rica
In Costa Rica, we faced unique challenges that those in the U.S. and Canada might not experience. The narrow, curvy roads and the need for constant GPS monitoring added complexity to our travels. Ensuring the bus could handle the terrain required careful planning and frequent consultations with local truck drivers. One memorable moment was navigating the mountainous roads near the Monteverde Cloud Forest. The sharp turns and steep inclines tested our driving skills and the bus’s capabilities, but the awe-inspiring views and the magical atmosphere made it a rewarding experience.
Navigating the Unexpected
Our travels have taught us to expect the unexpected. Mechanical issues, road closures, and weather changes are all part of the journey. One particular incident in Costa Rica stands out. We were traveling along a coastal road when a sudden downpour turned the road into a muddy quagmire. Our 45-foot bus was not designed for off-road conditions, and we quickly found ourselves stuck. With the help of some local farmers and their tractors, we managed to get back on solid ground. This experience reinforced the importance of community and the kindness of strangers.
Why Jajadabus?
Our decision to convert a bus instead of opting for a smaller vehicle was driven by our desire for comfort and space. We wanted a home that accommodated all our needs without compromising mobility. The 45-foot-long MCI J4500 Coach provided the perfect balance of durability, space, and adaptability. It has allowed us to live a minimalist lifestyle while still enjoying the comforts of a well-equipped home.
A Home for All Seasons
Jajadabus is more than just a vehicle; it’s our sanctuary. Its well-thought-out design and the incorporation of modern amenities make it a comfortable and functional home. With its 360-degree view, the kitchen allows us to cook and dine with ever-changing backdrops. With its custom king-sized bed, the bedroom ensures a restful night’s sleep, no matter where we are parked.



From Quebec to Ushuaïa
Our adventure started with a challenging journey from Quebec to Ushuaïa, Argentina. Despite the difficulties, including a long-distance relationship during the pandemic, we meticulously planned and executed our conversion.
Embracing a Minimalist Lifestyle
We now live a minimalist lifestyle, consuming less energy and water than in a traditional home. Living on the road has taught us the value of simplicity. Our minimalist lifestyle allows us to focus on what truly matters: experiences, relationships, and personal growth. We’ve learned to live with less, prioritizing quality over quantity. The 33 cabinets in our bus hold everything we need, carefully organized and easily accessible. Each item has its place, and no space is wasted.
The Joys of Connections
One of the greatest joys of our journey has been the connections we’ve made along the way. Fellow travelers, locals, and other bus enthusiasts have enriched our experiences and broadened our perspectives. Sharing stories, tips, and a meal with newfound friends has created a sense of community and belonging, even as we roam from place to place.

Challenges and Rewards
Every journey has its challenges, and ours is no exception. Mechanical breakdowns, navigating unfamiliar roads, and dealing with unpredictable weather are all part of the excitement and the adventure. However, each challenge is a learning opportunity and a chance to grow. The rewards far outweigh the difficulties. The freedom to explore, the beauty of nature, and the satisfaction of overcoming obstacles make every moment worthwhile.
Future Plans
As we look to the future, our journey is far from over. We plan to explore South America more and other new continents. We are pursuing the dream of converting Jajadabus to full electric, eliminating the need to carry propane. We want to continue pushing the boundaries of sustainable living while enjoying the freedom and adventure of life on the road.
Conclusion Our journey with Jajadabus has been nothing short of extraordinary. From the initial dream to the meticulous planning and execution, every step has been a testament to our dedication and passion. The 2004 MCI J4500 Coach has become more than just a vehicle; it’s our home, sanctuary, and ticket to adventure. Living on the road has enriched our lives in countless ways, offering us a unique perspective on the world and ourselves.
We’ve faced challenges head-on, from navigating narrow, winding roads to dealing with mechanical issues, but each obstacle has taught us valuable lessons. The freedom to explore new places, meet fascinating people, and experience different cultures has been incredibly rewarding. Our minimalist lifestyle has allowed us to focus on what truly matters, prioritizing experiences and relationships over material possessions.
As we continue our journey, we look forward to new adventures and discovering more of South America. Our story is a testament to the power of dreams, hard work, and the pursuit of freedom. We hope it inspires others to embark on their own journeys and embrace the extraordinary possibilities life on the road offers.
