In a nutshell, here is what happens if you save the money and don’t do it:
The truck will eventually fail. You will have to pay more than that to have a shop chisel the mud off anyway and in most cases it will be $450. You will pay between $4,000 and $6,000 for the repair.
The truck will be down a minimum of 3 days, and probably 7 depending on labor and parts availability; and guess what: For all this down time, inconvenience and money spent you will look under your truck and only 30% of it will be clean, and the rest will be still mud packed.
The components that the mud covers start to fail because they cant operate in that condition and you get to give our shop (or another shop) more money again.
In the business world right now, and all of the ways we are trying to cut costs and be more efficient, you can’t have this not be part of your scheduled maintenance. You used to be able to get away with this but operating costs need to be looked at by all companies, and this is a sure fire way to repair bills and save you thousands of dollars in down time.
