Instead of moving forward with the repair, customer is simply going to sell the machine as is.
We have no way of knowing what remaining issues their are until the machine would continue to be worked on.

In summary the parts alone are worth more than $2500.
If you removed the engine and sold as it, the water pump sold as is, and the vacuum pump sold as is, the vacuum waste tank, these parts alone would yield more money than $2500.
This is an excellent buy for someone whom does not mind working on truck mounts.
