In my Pik, I am forced back some and had some of the same problems.
I've got a Mini from Paraphernalia. It's about right for my setup. I
had to take the seatback out or have no headroom with the 'chute. I
have since rearranged cushions etc. and have the seatback in place. I
can get in and out easier and reach everything, now.
