Hello, the tailgate with my Sweden doesn’t stay up. Now that it’s colder it’s coming down right now. What can I do? Why doesn’t the 850 have a gas pressure lifter? Or are they hidden in the side bars? Has any of you ever built in? Have still those of my old 240 he. How do I get the wash nozzle from the tailgate. The nozzle is closed. Water is on to the back. Have opened the small flap on the right handle and removed the hose from the connector. full water power. Nothing comes out of the nozzle. Thanks for your tips.
