Uploaded December 2024 | Updated September 2026, 1 day ago
A few weeks ago, I took a trip up to Big Bear to test out the Sparks Overland prototype diesel heater in the crisp mountain air. This was my first time putting this heater to the test, and I paired it with my trusted Roamin Home canvas wall tent for a true cold-weather camping experience.

For those of you who’ve followed my channel, you know I don’t hold back when reviewing diesel heaters—I’m a tough critic and expect top performance. So, how does the Sparks Overland prototype stack up? Can it keep you warm in extreme conditions?

In this video, I’ll break down my first impressions, performance observations, and whether this heater lives up to the hype. If you’re considering a diesel heater for your overlanding or winter camping adventures, you’ll want to see how this one fares in the wild!
