Our truck tent poles are designed to be the perfect fit, even if this means they may feel tight during set-up. Please ensure not to force any pole during set-up, and ensure the right poles are being put in the correct places. Ensure the vestibule pole is set-up on the outside of your tailgate wire, rather than the inside as this causes too much tension in the pole. Align the tent to the truck bed carefully before tightening the straps. Ensure the vestibule pole is in the middle of the main pocket before inserting the ends into the side pockets.
