Not everything Thor does makes sense. However, in the past, you have not been able to rely on the info on the Thor site. I am not sure they ever changed the 24.1 from a E-350 to a 450 in the literature. My Vegas E-350 was always right at the max weight for the chassis when I weighted it. My E-450 Axis is 2000 lbs light in the rear. I like that. I would not want to go back to a 350.
