I've got a Grandby on a 3/4 ton short bed Dodge.
It works - but most of the camper weight is carried by the rear suspension. This results in the front being a bit light, and the rear a bit heavy - and you can really tell the difference, especially off road. It's not scary "OMG I'm gonna die" bad - but it sure would handle better if some of the weight could be moved to the front axle, especially off road. Airbags (or stiffer springs) will help, so would a heavier sway-bar on the rear.
One other thing to remember - if you leave your tailgate on (as shown in one of the pictures that Stan posted above), be sure you can lower your spare tire with the tailgate down before you load the camper.
