What is the smallest truck that can safely and legally tow around 35k (trailer weight plus load)? I have been hauling my equipment and my pickup to our jobs on a semi with a 53' step deck. It works but is hard to get into a lot of the places I need to get into and I got to thinking what if I bought a larger truck that could tow my equipment and still be able to use it as a work truck to drive back and forth to the job and such. My equipment weighs around 25k and would fit on a 30' trailer. I figure a 30' trailer that can handle that much weight is going to weigh close to 10k. I was researching the ram 4500, 5500, etc and while they have crazy payload capacity the are actually rated to tow less than the 3500 which is rated to tow around 30k. Seems strange to me the 4500 and 5500 are only rated to tow around 26k I think. The F-450 is rated to tow 31k and change. Is there something out there that is smaller than a single axle semi that can tow 35k and is small enough to be used as a normal truck? It would not really be my daily driver I have a another truck for that but when working I would drive it around 50 miles a day and would need to park it at motels, restaurants, etc so I don't want something huge.
