I wonder how they stay in business especially given that the cabs are a lot heavier than ours with those motorhome cabs.
I don’t think they are that much heavier, if at all believe it or not. If you see them vibrating down a rough interstate they wobble so much they look like they are made of tissue paper!
Volvo do make a lift axle 6x4 now so that’s probably it
