I'm thinking of getting a JL for traveling in with my dog and cat. Yes I know it will be tight and considered the option of an Ursa Minor top but the wait is long for the top. My question is this. What is the distance between the rear door and the back of the passenger seat with the seat moved all the way forward. Specification sites give legroom, headroom, and cargo volume but I need to know if I can fit my 6'6" frame on a makeshift bed in there. If it isn't long enough, have people removed the front passenger seat and extended the cargo area? Thanks in advance.
