FOR SALE — 2003 Peterbilt 378 • CAT C15 6NZ • Oilfield Ready
Fort St. John, BC • Serious Buyers Only

WORK OUTLOOK — U.S. & CANADA (2025–2026+)

UNITED STATES (TEXAS & LOUISIANA)
The U.S. Gulf Coast is in a sustained LNG and heavy-construction cycle. LNG export facilities in Texas and Louisiana are under construction or expanding, driving steady movement of pipe, steel, modules, concrete, and heavy equipment. Work continues beyond construction through operations, maintenance, ports, roads, industrial builds, and mining—keeping demand strong for heavy-spec trucks.

WESTERN CANADA (BC & ALBERTA)
Western Canada remains in a long-term build and maintenance cycle. LNG Canada is live and commissioning. Woodfibre LNG is under construction, with Cedar LNG advancing into early construction. Across BC and Alberta, including the Montney, ongoing work includes pad builds, roads, water hauling, equipment moves, pipeline integrity digs, compressor stations, mining, utilities, and northern infrastructure.

BOTTOM LINE
LNG, natural gas infrastructure, oilfield maintenance, mining, and heavy construction are all active at once. This is a market where a reliable, oilfield-spec Peterbilt goes straight to work.

OWNER STATEMENT
This was my personal driver. I drove it like a workhorse, not a race car. Maintained to work every day in real oilfield conditions.
