Believe it or not, I have put in a full sized washer and dryer into the back of our wagon.
We purchased both thinking we would have to make two trips. We began to measure and with both seats moved forward a bit and the seats all down, there was room.
The key was to of course remove the rear head rests and just go VERY slowly to avoid scraping the interior.
The people at the loading dock were blown away. One guy said to his wife "we're gonna get one of those!"
