[Mr. 250r]

Here is a picture of a 2013 F-550 with a 1900+ lb bed plus a 2200+ lb drill as you can see there is no sag and its still sits correctly *Higher in the rear*, we also did a 2013 ram 5500 but i think it sat basically level i'll have to check again but it might of got picked up. So if the van body weighs somewhere within the.... 41-4500lb range i think you'll be fine on a 5500 setup but that's also all the weight on the rear so the van body will be spread to the front as well but i still think it would be okay. We haven't had any silverado's in basically ever so i couldn't tell you about them but i can only assume there all about the same
