1. Cover or tape any sharp edges on your RV that could wear against your RV cover. Be sure to lower any roof antennas.2. Carefully climb up on the roof and take your cover out of its storage bag. Place the rolled-up cover at the front center of the roof and unroll down the center of the RV.3. Starting at the front, unfold your cover from the center outwards. Continue unfolding the cover as you work toward the back, letting it fall over the sides of your RV. Make sure the corners of the cover are at the corners of your RV.4. Climb down the rear ladder and locate the ladder cap. (The cap helps keep the top of the ladder from stressing the cover). Fit it over the ladder top and attach it to the rungs with the hook and loop straps. Now pull the back end of the cover down the back of your RV.5. Your cover is equipped with triple zippers on the front side panels. These zippers allow the cover to fit RVs with mirrors that do not fold against the RV. Zip all three zippers down to the mirror height, then zip the bottom zipper to the bottom of the cover. Create an opening at the mirror height by zipping the top zipper up slightly and the center zipper down slightly. Slip the opening over the mirror and close the top and bottom zippers around the mirror post. Finish by zipping all the panels closed on your cover then pull the elasticized corners down over both bumpers of your RV.6. Tie an end of one of the supplied pre-cut ropes onto one of the D-rings along the bottom hem. Put a small rock in the provided toss bag, close the top and tie the free end of the rope to the bag D-ring. Now toss the bag and rope under your RV to the D-ring on the opposite side. Take the rope off the bag and tie it to the D-ring. Repeat with the remaining D-rings.7. Adjust the strap length on the white tension panels across the front and back to fit your RV. Don’t over tighten—the straps should be snug, not drum tight. To attach the straps into the side release buckles just insert the clip into the buckle. To release the buckle press the buttons on both sides and pull the clip out of the buckle.
