Start with a route, not a purchase
Your first vehicle is the KROK V-15 Urban van. Check cargo weight, volume and body requirements before expanding. The KROK R-60 City unlocks at level 2; tractor units follow from level 3.
Build a complete crew
Every vehicle needs a driver and must be in the departure city. Vans and rigid trucks use their fixed bodies; tractors also need a compatible trailer. The readiness line on each contract explains what is missing.
Protect the first margin
The payout is not profit. Diesel, wages, roads and wear come out of it. Prefer a feasible job with time in reserve over a tempting express contract; reputation and cash are easier to grow when the first delivery lands cleanly.
