Dog in crate on travel trailer bumper! If anyone here

Think of the vacuum behind the trailer. Then think of the carbon monoxide being discharged from the tow vehicle. Hopefully the dog survives the trip.

A modern vehicle in proper repair emits basically no carbon monoxide while cruisimg down the road. The computer controls and catalytic converter take care of that. Diesels characteristicslly produce very little CO because the combustion by design has an excess of air.
