Re: WK Interior Dimensions re twin bed
I went ahead and drove over there thinking worst case I'll just strap them to the roof. They actually fit inside the Jeep easily, although a little long. I had to move the front seats up nearly all the way which had my knees pressed against the dash and gut nearly touching the steering wheel, but it was a relatively short drive and worth the inconvenience to keep them out of the weather. I'll bet you could fit up to a full size mattress in the WK, given a full is the same length as a twin and just a little wider.
