thanks for all of the replies. It has been a crazy week but I finally got a chance to check it out and I was able to take the headrest off. I used a small nail to release the headrest "latch"? but then it was just bumping into the rear window. I had to go into the truck to release the seat and edge it forward a bit....What a crazy design.
I like to tie down a large towel and place the kid's carseats on top. Kinda trashy looking (reminds me of the old platic covered sofas) but ever since one left 2 crayons on the seat I try to be more careful. BTW, crayons + 2 days parking outside in August heat = really bad stain.
On my other cars, I sometimes take them off on long trips to improve visability. With this car's visability out the back, it is probably the one car that needs it the most but I don't think I will be going through that type of hassle.
Thanks again for the help.
