Vehicle Life Expectancies

[Little Jo]

Hi David

When I was restoring my 1942 MB Willys Jeep and doing research on the vehicle, I heard or read somewhere that in normal active service areas the life span of a jeep was 6 months. However the life span of a Jeep on "D-Day" it was down to 10 hours. I have heard similar stories from others but I can't confirm how accurate these figures are.

Cheers

I would suggest they are just stories. The vehicle's longevity (Jeeps and CMPs, along with just about every other military vehicle made) indicate that they were not made for 6 months use. Why would you waste putting grease nipples onto U joints if they were not expected to be around more than a year?

As to combat life expectancy, I would suggest that there are so many variables to combat conditions, that there would be no hard and fast numbers.

think about all the vehicles that are still on board the ships they left port on all at the bottom with almost 0 miles,

I see both sides of the discussion here. Of course vehicles were engineered to be the best they could be. It is fascinating though to look at the statistics and understand the average lifespan of vehicles due to all of the variables involved.
As Frank point out, you have Jeeps for example with "0" miles on the bottom of the Atlantic and then there are those that have survived until today with many thousands on them. I am sure planners of the day had this all figured out to include all the facets from shipping losses to maintenance to wear and tear.
If one is to study the maintenance manuals for example, these do give interesting insight as to when things like major overhauls were expected.
