Lightbulb Heat exchanger for moisture control?

While pondering the issues of condensation on windows and within cold walls causing soaked insulation, I remembered about a device I read about in researching ultra-energy-efficient homes: an air-air heat exchanger. What it does is blows fresh outside air through a radiator-like device that has stale interior air blowing through as well. This allows for exchanging the air within an enclosed space, without blowing all the heat (or cold depending on season) out along with it. This might be an elegant solution if condensation or stale air is a problem, particularly when weather conditions require heavy use of heating or A/C. Any installation will have to accomodate condensation within the exchanger, but better there, than on windows and inside walls.

Has anyone ever thought of doing this on a trailer? Here is one webpage I found for examples in a hurry; a deeper search should find models better suited to a trailer installation. Heat Recovery Ventilators (HRVs) | iaqsource.com - Aprilaire, Honeywell, Trion Air Bear, Bryant, Carrier, Trane Filters and IAQ products

Here is the previous discussion. I think it's a good place to start.
