I say no back seat for mine. I looked at it today and with the dse tub/quad it could work fairly easy but the dse roll bar leaves me 2 1/2" for lower seat to lock in and the stock one I have is 5" big problem. I sure buckets or something could work. After reading this post the rear passenger " my two kids" head would be about 2" from the cage. Ya I probably will not get in a collision but they ever got injured and I knew prior I would never forgive myself (LOL more room for some subs). here is a picture of it.
