Yes, you can! When installed and secured properly, the Softopper is rated for highway speeds.

We do not make a top for the Rambox trucks. The box system is incompatible with the placement of our bedrails.

All of our Softoppers (excluding the older Ridgeline, as they retract backwards) are compatible with a 5th wheel trailer. Once the Softopper is retracted you may want to remove the back half of your bedrails to reduce the risk of scratching during sharp turns. Take the clamps from the back half of the bedrails, loosen clamps on the front half for a little wiggle room, then press on the pushpin to remove. Keep the back half of bedrails somewhere safe during travel. 

You can take the Softopper through a touchless carwash. We do recommend you rinse off any residual waxes or cleaning agents off the windows right after going through the car wash. If you’d rather wash it at home, we recommend a mixture of water and dish soap. You can also do an extra cleaning/polishing with our new cleaning products found here: https://softopper.com/introducing-the-st-cleaning-care-line/ 

To clean the windows use the water and dish soap mixture with a microfiber cloth. We also sell a special cleaner for vinyl windows you can use: https://softopper.com/products/st-vinyl-window-cleaner-universal/?sku=RP-CLNWN-STD
