Hidden Diesel Heater Install: Overland Trailer Upgrade

In this video, I’m upgrading our overland trailer with a Chinese diesel heater hidden completely inside the tongue box. We wanted a stealth heating solution for winter camping that wouldn’t clutter up the rig, and this DIY install keeps everything clean and protected for off-road use. In this install, we cover: How to mount a diesel heater plate in a tight space Modifying a tongue box for proper airflow and exhaust Routing fuel lines and wiring for a 'factory' look Tips for keeping your heater safe on the trail ⚠️ WAIT! It wasn’t all smooth sailing... While the mounting looks clean, getting this heater to actually run was a different story. Make sure you subscribe and turn on notifications for the next video, where we troubleshoot the failures, fuel leaks, and error codes that popped up immediately after this install!
