MountainProof solutions for winter, off-grid, and
extreme cold living.
Field-tested guides, gear reviews, and real fixes from life at 7,000 feet.
Real systems. Real winters. No theory.
Systems That Keep Working When Winter Tries to Shut Them Down
Real-world guides for water, power, heat, and mobility in extreme cold and high-altitude environments.
Winter RV Systems
Keep Your Rig Alive Below Freezing
Water, heat, power, and insulation strategies for RVs living through real winters — not just shoulder season camping.
Home & Cabin Freeze Protection
Protect the Systems That Matter Most
From frozen pipes to power outages, we break down how to harden homes and cabins against extreme cold.
Field Repairs & Emergency Fixes
Fix What Breaks — Fast
Step-by-step field fixes for frozen lines, burst fittings, and cold-weather failures when help isn’t coming.
Built Where Failure Has Consequences
ColdTech Systems documents what works in real cold-weather environments: where water, heat, and power failures aren’t inconveniences, they’re emergencies.
Real Systems, Not Theory
Everything published here comes from systems that operate through real winters — not lab tests, not spec sheets, not best-case assumptions.
Tested Under Load
ColdTech methods are stress-tested by altitude, wind, freeze-thaw cycles, and limited access to help or parts.
Designed for When Help Isn’t Coming
These guides assume you’re on your own — overnight freezes, power loss, frozen lines, and no quick fixes.
Essential ColdTech Guides
Start with these field-tested articles — built for real winter conditions and real systems under load.
- How to Winterize an RV for Sub-Zero Temperatures
- Preventing Frozen Water Lines at High Altitude
- The Cold-Weather Field Kit: Tools That Don’t Fail
- Heat Tape, Insulation, and When They Actually Work
ColdTech Systems publishes field-tested guides on winter systems, off-grid resilience, and cold-weather infrastructure. New articles are added as they’re proven in real conditions.
ColdTech Systems documents what survives winter. TundrCore Resilience Group builds and maintains it in the field.
