Not in the Sportage range although i have carried long loads (3mtr) by moving the passenger seat as far forward as possible, remove the headrest then lower the back as far back as possible, pretty flat after that.
Manage to get my pole holdall in straight.. 6feet long... behind passenger seat by putting seat as far forward as it will go and winding the recliner as far forward as it goes, still got a little space behind it so it doesn't rub on the inside of tailgate.
Thanks. Good to know that the seat reclines enough to be pretty flat. If I try and do the same thing in my Skoda Superb, the headrest is a real struggle to remove, and the seat sticks up a fair amount.
