Charlene Bower brings decades of real-world offroad experience, and teaches in a way that’s approachable, fun, and easy to apply to your own adventures. Her style is to break down complex topics into simple steps, mix in plenty of Pro Tips, and make sure every class is interactive and engaging. She teaches at the intermediate level that beginners will understand and seasoned Vanlifers will gain from. You won’t just hear theory and concepts, you’ll walk away with usable skills, a clearer mindset, and the confidence to tackle challenges on your own.
4WD / AWD Powertrain Basics – Understand how your van puts power to the ground. We’ll break down the differences between 4WD and AWD, explain drivetrain concepts in simple terms, and show when (and when not) to use different settings. You’ll build confidence in your van’s capabilities (and limitations) before the terrain tests you.
Tires, Wheels, Brakes & Suspension – Your only contact with the ground matters most. Learn how to choose the right tire, read ratings, understand wheel offset, and evaluate brake upgrades for safety and control on the trail. Then we travel into suspension dynamics and when and why it matters the most. Airing down is usually taught in another section, but will be added for this in-person version.
Recovery Tools: Smart Shopping – Don’t waste money or space on the wrong gear. We’ll teach you how to shop by vehicle weight, read labels, and understand the “minimum kit” for your van. Then build up your recovery kit to include more opportunity and how to add a winch (and winch accessories) the smart way. Tons of Pro Tips on how to use the tools included!
Field Fixes: Getting Off the Trail – Sometimes it’s about patching things together just enough to get home. Learn practical field fixes: plugging or patching a tire, creative repairs with zip ties, duct tape, and JB Weld. We will dive into some electrical fixes like replacing fuses, and the art of safe towing. Learn simple roadside and trail repairs, emergency planning, and how to keep moving when the unexpected happens.
Responsible Recreation: Protecting the Trails We Love – Your adventures depend on access. This session brings it all home with principles of how to travel responsibly, support trail organizations, and put the TREAD principles into action so van lifers can enjoy these places for years to come. Plus, we’ll share resources to stay connected and keep building your skills. (This is not the boring class you would expect with this title! Very important concepts to ponder.)
