The Thule Ascent 1100 was exactly what I wanted. I checked the Thule website and it seemed that it would fit my 2005 Honda Pilot. When I got the box it did not fit. There is limited adjustment to the mounting and you can't make it clear the back hatch. When I called Thule they said it would fit the rack but it wouldn't clear the hatch. They said only the Boxter would fit for sure. That wasn't the shape I wanted. Backcountry was very helpful and had the box shipped back for credit. I called several other manufacturers and was unable to get accurate dimensions to determine if their boxes would fit. If they would just give dimensions from the back of the box to the front and rear mounts (their range) you could see if it would fit. Finally, I had a neighbor with a Thule Frontier Box who let me test fit it. I had to drill some new holes for mounting, but it fits fine now.
