A dump truck or transfer rig that loads there may well be parked at a yard off the quarry road when you call; give us that address rather than driving it in, and we will meet it there.
Roblar Quarry LLC, a sand and gravel operation, sits 7.2 miles out in the same westerly direction according to the Mine Safety and Health Administration. If your truck has hauled aggregate from Roblar, photograph the bed, the tailgate and the VIN plate, and send the registration card with the pictures so we can match the unit to its paperwork.
Farther up the valley, the Mine Safety and Health Administration places Mark West Quarry 17.4 miles north. Owners who run between Mark West and the Penngrove side can keep the truck working until the sale is settled; tell us which end of the route it will be parked at on collection day.
Seventy-eight small outfits, mostly in-state
For a seller here that usually means a California-plated truck that has stayed inside the state, so the California registration card and the title are the two papers to find first.
Eighteen of those carriers are private fleets moving their own goods, per FMCSA’s census. A contractor or a farm that owns one or two trucks for its own work sells to us the same way a for-hire operator does; the person named on the title signs, and we collect from the shop or barn.
The three biggest Penngrove fleets in the census run 12, 8 and 8 power units. An owner selling several trucks at once can send one list of VINs, plates and locations, and each unit is handled on that one list.
Lumber, machinery and hay on the manifests
General freight leads the cargo declared by Penngrove carriers in FMCSA’s census, with 11 carriers, followed by logs, poles, beams and lumber at 9. A log truck or a flatbed with stakes and bunks is as welcome as a box truck; photograph the trailer setup along with the tractor, since the equipment fitted tells us what the truck was built to do.
Seven local carriers list machinery and large objects, and six list grain, feed and hay, in FMCSA’s carrier census. Lowboy tractors and hay trucks often sit on a ranch or a job site between loads, so tell us whether the gate is locked and who can open it for the pickup.
The census also logs 4 carriers newly registered in Penngrove in 2025 and 1 in 2024. A recently started operator selling a financed truck should have the lienholder’s name and the lender’s release ready to go with the title.
Sixteen Penngrove carriers report mileage to FMCSA, and the median among them is 6,125 miles a truck for the year. A unit that covers that kind of distance spends much of its time parked at home, which is useful to us: tell us where it sits most days and we schedule collection there.
In FMCSA roadside inspection records from September 2024 to August 2026, 55 trucks tied to Penngrove carriers were inspected, with a median model year of 2018 and 30.9 percent ten or more years old. Have the model year, the engine make and the odometer reading on hand when you contact us, since those three figures start every conversation.
Driver listings in the federal carrier census put 28 drivers inside a hundred-mile radius and 106 beyond it. If your truck is out on a long run when you decide to sell, give us the date it will be back in Sonoma County and we will plan around that.
The State of California Department of Motor Vehicles runs its Petaluma field office at 715 - J Southpoint Boulevard, Petaluma, 94954, 3.3 miles from Penngrove. A lost California title is replaced through the DMV field offices, and Petaluma is the counter nearest town; ask for the duplicate before the sale so the paper is in hand on collection day.
When the name on the title is a business, bring proof that you can sign for it to the Petaluma office or to us. A signed title, a current registration and a photo ID from the seller are the three things we ask for at pickup.
Dump trucks, water trucks and delivery straight trucks belong to that kind of work, and we buy each of them from the owner directly.
A builder retiring a truck from one of those firms should gather the service invoices kept at the office, since a folder of maintenance records answers questions before we have to ask them.
Across Sonoma County, USDA’s 2022 Census of Agriculture counts 3,097 farms, and milk, cattle and cut flowers lead the county’s farm sales. Milk tankers, cattle trucks and refrigerated flower haulers parked on a dairy or nursery near Penngrove can be collected from the farm itself.
To the east, the North American Rail Network maintained by the Federal Railroad Administration and the Bureau of Transportation Statistics shows NAPA YARD 21.2 miles from Penngrove and LOMBARD YARD 23.4 miles out. A tractor that shuttles loads to either yard can be picked up on that side of the hills; send us the street address of the lot it is stored on.
Napa Quarry, an industrial-mineral mine the Mine Safety and Health Administration places 21.6 miles east, adds another haul route. If your truck is kept closer to Napa than to Penngrove, the sale works the same, with the title signed wherever you are and the truck collected where it is parked.
California clean-truck rules, in plain terms
Under a federal court filing, the state’s full zero-emission sales requirement for medium- and heavy-duty trucks has its enforcement paused.
Penngrove owners selling a diesel truck today do not need to settle any of these rules before the sale; bring the title and registration as usual.
