Is Your Rig Ready for Winter?
Fall is here, and colder Northern Arizona temperatures aren’t far behind. Now’s the time to make sure your rig is ready.
At Southwest Truck & RV, we specialize in medium- and heavy-duty trucks—gas and diesel—from work trucks to big rigs and fleet vehicles. Before winter arrives, let us check the systems cold weather can punish: batteries and charging systems, cooling systems and antifreeze protection, belts and hoses, brakes, tires, fluids, and more.
For commercial vehicles, preventive maintenance isn’t just about avoiding repairs. Downtime costs money. A little attention now can help prevent an expensive roadside surprise later.
And don’t forget your RV. If it’s going to spend the winter parked in freezing temperatures, proper winterization can protect plumbing, batteries, fluids, and other components from costly damage.
