A truck mounted drilling rig can look strong in a brochure and still fail in the field if the compressor, chassis, mast, fuel tank, and service layout are not checked as one working system.
Most drilling rig delays are not random. They start with lazy model descriptions, vague invoices, wrong shipping terms, and a broker who sees the file too late. Here is the import playbook I would use before wiring a deposit.
Buyers obsess over purchase price because it is visible. I care more about the bill that shows up 18 months later: diesel, downtime, mechanic hours, rod abuse, weak control in mixed geology, and the lost revenue that never makes it into the quote comparison.
Most distributors buy the wrong rig for the right reason: they over-index on maximum depth and underwrite the wrong customer segment. Here is the harder, better way to build a water well drilling rig line that actually sells.
