I'm sure the dude spent a bit of time on it. Slope exactly matches rear seat slant so it fits nicely in. Perfectly carpeted. Just wrong size.
I actually talked to the guy today. Said I ended up taking his box out and putting my prefab box in because the one he built, while looking awesome, was way too boomy. I also said that the cu feet were wrong on it and it should have been less. He just looked at me with a dazed kind of look...kind of like he was amazed that I actually knew a bit about it..and kind of made small talk. At one point said that "outside measurements dont matter...its the volume that matters". Yes..and yours was off!
No love on a replacment from him...but I didnt expect it. He did a few other things on the install to take care of me that I'm just gonna eat it. But I'm glad I brought it up to him.
