Its true their lungs will fill with fluid.. This starts happening after about 6 hrs.. As far as how long they will stay alive depends on the horse.. They are not gonna die from just sleeping.. Usually the horse will have other problems that caused him to lay down in the first place.. Uh.....no.....
1940 - Working from a Bantam Car Company design, Willys contracts to build military Jeeps for the war and produces about 360,000 vehicles by 1945. 1945 - Willys-Overland begins producing the Civilian Jeep (CJ) line, with the introduction of the CJ2A model. 1946 - Production begins on the Willys Jeep Wagon. Over 300,000 are manufactured between 1946 and 1965.
One of the most enjoyable Jeeps to work with today is the Jeep YJ Wrangler, as built from 1987 to 1995. The generous YJ engine bay allows for a comfortable, clean fit for GM Small Block V6, V8 and even Big Block V8 engines.
