Question: can you fit a king size mattress in a transit van?
Answer: In the US, though, there is no way a king-size mattress will lie flat in the back of a Cargo. ... If the longest side of the king-size mattress went along the floor of the van, you should have about 20" to play with. The mattress is 80" and the shortest van floor, even in a short wheelbase, is about 100".
