The Mercedes Actros is considered a heavy duty truck .

I think he should consider checking the truck coverage of a Maxi Sys CV because the regular Maxi Sys does not include very much commercial vehicle coverage.
From google translate I think he asked how much it costs for the machine that he needs to scan that truck. I think it ranges between $3,000 and $4000 USD.
