Are there any people on this forum who work in trucking? I know you've experienced breakdowns, too, and I'm curious who you turned to in those situations. I would be very grateful for your response.
What kind of breakdowns have you already had? I had a problem with my trailer, but I was lucky to notice it early. There was an issue with the brake system, so I called Mobile Wrench, a company that provides mobile diesel repair (https://mobilewrenchfleet.com/mobile-diesel-mechanic/) services. They arrived quickly and repaired everything I needed, so I was able to go on my truck trip right away. If you need an urgent repair on your truck, you can contact them.
