Editorial Role
What Sarah Jenkins, CEMP Covers
Sarah Jenkins, CEMP contributes practical heavy equipment guidance focused on specs, maintenance intervals, diagnostic workflows, fleet operating costs, and model-to-model comparison decisions. Pages credited here are intended for equipment owners, fleet managers, mechanics, estimators, and buyers who need clear numbers before checking the final OEM manual or dealer documentation.
Technical pages are written to separate verified specification fields from editorial planning estimates such as fuel burn and hourly operating cost. Critical values such as lift capacity, transport dimensions, fluid specifications, torque values, and safety procedures should always be verified against the exact serial range and configuration.
