Iona Farm and Idaho Falls RV Supply Company Each Mark 100 Years in Operation
Two East Idaho Institutions Reach Century Milestones Amid Modern Challenges
IONA, Idaho — Two eastern Idaho businesses are celebrating a combined two centuries of service to their communities, with a century-old farm in Iona earning state recognition and an Idaho Falls RV supply company preparing a centennial celebration for customers next month.
Haderlie Farms in Iona — a 3,000-acre operation growing wheat, barley, and alfalfa — was recently named an “Idaho Century Farm” by the Idaho State Historical Society, an honor given to farms across Idaho that have remained in continuous operation for 100 years or more. The farm was one of 11 recipients of the award in 2025.
Tim Haderlie, the farm’s current owner, traced the operation’s roots to his grandfather, Henry Haderlie, who purchased the original 80 acres that would become the foundation of today’s sprawling agricultural enterprise. What began as a modest family parcel has grown and diversified across four generations, now stretching across 3,000 acres in Bonneville County.
Tim Haderlie shared the story of the farm’s growth and his memories of growing up working the land in a recent episode of It’s Worth Mentioning, a locally produced show covering stories from across eastern Idaho. He described what he finds most rewarding about a life in agriculture and reflected on what the century designation means to his family — with a particular sense of pride in its multigenerational continuity. A photo shared by the family shows Tim alongside his father, son, and grandson, with his father holding a photograph of Henry Haderlie himself.
Drought Declaration Adds Weight to Farm’s Achievement
The centennial milestone comes at a difficult time for Idaho agriculture. The state has declared a drought emergency across all 44 counties following record-low snowpack levels, placing added pressure on farming operations throughout Bonneville County and the broader Snake River region. Haderlie addressed the challenges the emergency drought declaration poses for operations like his, where water availability is critical for crops including the alfalfa and grain that anchor the farm’s production.
The recognition from the Idaho State Historical Society provides a moment of reflection and pride even as farmers navigate an uncertain growing season. The Idaho Century Farm designation is not given lightly — it acknowledges farms that have endured drought, economic downturns, changing markets, and generational transitions while remaining productive and family-operated.
Haderlie also spoke about the future, specifically about passing the operation on to his children and grandchildren — continuing a tradition of family stewardship that has now spanned more than a century of Idaho agricultural history. For communities like Iona, where farming remains central to local identity and the regional economy, that kind of continuity carries deep significance. Stories like Haderlie Farms illustrate the enduring relationship between East Idaho families and the land — a connection that parallels community efforts like the Idaho Falls art show benefiting Happyville Farm, where local supporters have rallied around agricultural roots through creative fundraising.
State Trailer RV Marks 100 Years With Idaho Falls Celebration
The second centennial story comes from State Trailer RV & Outdoor Supply, which is marking its 100th anniversary in 2026. Mark Hult, president of the company, traced the business’s origins to Salt Lake City in 1926 before its expansion into eastern Idaho. State Trailer has operated locations in both Idaho Falls and Pocatello since 2008, serving customers across the region as an RV parts supplier and service center.
Hult is hosting a centennial celebration at the Idaho Falls store on May 1, inviting the community to mark the milestone alongside the company. He reflected on the business’s century-long history, his own memories of working with his father, and how he eventually took over leadership and guided the company’s growth and expansion into the Idaho market.
Like Haderlie Farms, State Trailer’s story is one of multigenerational investment and community-rooted business — values that have long defined commerce in Bonneville County and across eastern Idaho. For more statewide coverage of Idaho businesses and agricultural milestones, visit Idaho News.
What Comes Next
Haderlie Farms will continue navigating the 2026 growing season under Idaho’s statewide drought emergency declaration, with water management and crop production among the most pressing concerns for the Iona operation. State Trailer RV & Outdoor Supply’s centennial celebration is scheduled for May 1 at its Idaho Falls location, where customers and community members are welcome to participate in marking the company’s 100-year anniversary. Both milestones serve as reminders of the agricultural and small-business traditions that have shaped Bonneville County for generations.
