Exhaust hose for HMMWV garage startup?

[M1165A1]

Anyone using a flexible hose like a Fume-a-Vent for HMMWV startup?

My HMMWV is garaged and when started will make smoke. I can't leave my garage doors open to vent out the garage because of very cold temps in winter. Same issue with working in the garage during the winter, can't leave the doors open.

I am thinking a simple exhaust hose for startup - looking for recommendations as to product, or any practical experience?

Just need a blower fan that can take a heat resistant hose input and blows to outside. Nothing really fancy about it; just gotta move the air.
A hose that you can clamp down around the exhaust would also work, but I wouldn't trust it running the truck for any length of time; much better to have forced ventilation.

@Coug is definitely "on the money" with a blower fan in the pipeline to the outside. We installed a UV coating machine in the print shop with about 30 feet of pipe to the outdoors. Adding a "squirrel cage fan" about half way up the pipe greatly improves the exhausting efficiency.

The hardest part - especially in cold weather - is allowing as much AIR IN as you are trying to push AIR OUT. Always difficult to allow your nice warm garage air to get pumped outside....

A really good source of information is the Fire Service. They have trucks that are inside a building pumping exhaust into the air. The rooms the firefighters sleep in are generally upstairs. Smoke rises. Take a look at this article about indoor air quality.
