Are you talking about commercial semi trailer rigs or large RVs? It is made for RVs and will work with RVs of just about any size. You input the dimensions of your rig (including the truck if used) and RV 890 will determine the best route for your size rig. It will give you warnings for your route based on your size rig. It will also give warnings about crosswind areas and if you purchase the Garmin Drive App it will also give you traffic and weather information.
Sorry, there was a problem. Please try again later.No, this model is designed for passenger vehicles and RVs and does not provide any truck routing. Our Garmin dezl series offers custom truck routing for the size and weight of your rig. Just enter your truck profile (customizable by height, weight, length, width and hazardous materials) to find truck-preferred routes best suited for your rig and load.
Sorry, there was a problem. Please try again later.You can have multiple profiles that have distinct needs - for example height, width and/or weight. We have a 30' tow behind - if I use that profile, it'll keep me off tight twisty roads, not route through low bridges, or warn me if I venture onto roads that have weight restrictions. If you're a commercial driver, the database for services might be a bit irrelevant, as its focus is for RVs. Garmin might have a commercial version of this GPS, but it's probably more expensive.
