Never seen any cores available for TF trucks? You can make a core with a tight serpentine copper layout maybe, 1/4 or 3/8 tubing? It's just some hot water to blow over. Make it fit in the same space as the core, use larger copper tube on each end to accept the heater hose. never done this, just brainstorming. maybe an inlet valve to control flow rate so you can tweek it. Sounds like a crazy idea to me. Easy to make anyway if they don't make cores anymore. Only two leak points and they would be outside the cab. Eggs and pepper, I'm getting hungry for breakfast.
