The Otto Step is 18" wide by 16" deep with a 6" 2x2 stinger that fits snugly into any 2" trailer hitch receiver.  The step has notches that make it fit snuggly against the hitch receiver so there is no ground seen when looking down for the dog.  The extension is 22" in length and extends out far enough to clear all the tailgates that are out in the market to date.
