“With nearly eight years of full-time travel, I’ve had the opportunity of spending lots of cold nights in RV’s and vans. Frequently, this is in the mountains of Colorado, where a heater is critical to surviving the single-digit winter nights. I’ve used many popular heater types that run off propane and diesel. My current favorite is the Timberline heater by Elwell.

The easy accessibility of the diesel fuel, the same as my Sprinter van, makes it convenient always to have my heater ready to use. I no longer have to search for propane or fill extra tanks weekly. As long as my heater has fuel in the tank, I have heat at my fingertips. The Timberline heater is the best option for heating my van.”

Soft, hydronic heat: Count on consistent comfort even in the most adverse of climates.

The Timberline 1 SERIES uses the Autoterm Compact 5 heater to intelligently manage energy, performing seamlessly at high altitudes and sea level alike. Automated air handlers adjust output based on your climate, keeping comfort steady without you lifting a finger.

Need an extra boost? A supplemental 120V heating element kicks in when you’re plugged into shore power.

Set your temperature, head out on your adventure, and come back to reliable warmth and hot water every time.

Pecos Wilderness, Rociada, NM ⛰️🥾

This is where roughing it begins: cold air, breath in the dark, and sleeping under the stars.

From powered sites to fully off-grid destinations, the goal never changes: go farther, stay out longer, stay warm. Whether you’re parked at a campsite, pushing into overland country, or fully off-grid with a tent beside your rig, Timberline provides instant heat and continuous hot water, giving you the choice between raw wilderness and real at-home comfort.

With Timberline in your rig, warmth isn’t something you leave behind. It’s waiting for you after every hard trek.

Proud to be part of the Washougal Christmas Parade this year. 🎄

Kody and Josh put heart into preparing our trailer, the Cybertruck led the way, and our team walked the route handing out candy while the kids enjoyed the ride.

Events like this remind us how meaningful it is to be part of such a supportive community. We wrapped up the day with a pizza night at the warehouse—celebrating teamwork, the season, and delicious food.

Thank you again to our amazing community, and Merry Christmas!
