Is there enough room for a carseat/people to go in easily in these? I have been looking for a crew cab but it seems like the extended cabs are much better deals right now (looking at 1-3 year old trucks). I need a truck for work and to take my daughter to day care in. I'll probably keep it awhile so there will probably eventually be 2 kids in the back at somepoint. If I put the seat back to drive will the backseat be useless? I'm 6'. Thanks.
