Question:

Hey etrailer, my 2027 Tundra has the 5-1/2 foot bed and factory Deck Rail System. I don't want to order this and find out those rails are in the way. Will W85YH work with them? How does it hold up against water?

Hey Justin! Yes, the Westin Power Retractable Tonneau Cover # W85YH fits your 2027 Tundra with the 5-1/2' bed and Deck Rail System. It also fits Tundra models without the Deck Rail System. The cover has seals to help keep water out along with drain tubes that route water from the rails and canister out of the truck bed.

What do you typically haul with your Tundra?

Thanks for the quick response. I use a cargo basket for camping, and might add a rooftop tent down the road. Is there a good set of crossbars for this? More like a roof rack not a full ladder rack.

@Justin absolutely! The Westin Crossbars # W79ZK are specifically designed for the T-slots in these tonneau cover rails. They'll work great for your cargo basket and give you a platform for a rooftop tent as well.
