I have a small (2-3" high) curb-like step at the front edge (house end) of my garage. Not sure why, bit most newer houses seem to have it here in Georgetown, Texas...but it serves to stop my roll forward into the garage so I don't have to worry about hitting the back wall (provided I dont give it any gas)...
But I haven't had a garage in 20 years or more, but recently got a home with a garage I haven't filled with junk yet...so I fit in my 2014 EL. Just barely. I have enough room in front that I can squeeze by, as long as the truck is clean or I don't mind cleaning the grill/bumper with my pants. Only about 2-3 inches between the garage door and my hitch cover.
