I have that same kayline and have a few tips for you.
1) If you decide to drive it with the sides and back rolled up I suggest this: go to an upholstery shop and get a long strap and buckle made so you can tie the rear hoop to the floor. You could also use 2 straps and tie the corner of the hoop to the bedrail corners through some eyebolts or something..... The top will flop around a lot if you dont. This creates a bit of a problem though if your windshiled is not firm (I need to build some cage tie-ins for mine), if you tighten the strap(s) down too much, you will pull the windshild frame into the door window frames and make them bind a bit when opening and closing the doors.
2) I found that over time the velcro around the door frames tends to lose its hold. I rivited snaps to the frame and attached snaps to the top to keep it in place.
