Looks like you can order new replacement pole , and old style thumb screw w/hub kit . May get rid of friction clamp on new brella , like blueball said , doesn't hold . I found an old school cooler ,( 50ish at) Coleman I think still in box , and bought a red 50qt igloo at academy for 25 bucks for fish cooler . Yesterday was their first day out , believe they'll be fine. I will provide exact models and more test data later . The roto mold cooler hasn't left the bed of my truck in weeks. It's just to dang heavy . Guess I'm getting old .
