Brand new 2015  38/5 BSF 38.5.16H  demo truck on a Mercedes actros.

$357.000

I presume the American trucks still use the 12 volt electrical system. 

yes 12 volt on our trucks ill take a 40m too there just hard to find in decent shape

im trying to stay close to 200k

That is the bad thing. the rest of the world is using 24 volt on the trucks and pumps. so you are limited to the north american marked.
