Easy to install and works great. Very satisfied.

Love it

Absolutely the best hard truck bed cover on the market in my opinion. Not hard to set up. You can tell it's strong and durable. Locks in place. Smooth action when lined up properly. Pretty dam good on the water resistant side. Low profile that looks sharp. Extremely happy with purchase. had the best price and great customer service. Highly recommend this product as well as purchasing through!!

Rolling Tonneau

Install was straightforward, no issues. The flush mount design looks great. Hoping to get many years of performance.

Fantastic Cover and Buying Process

Shipping from Tonneau Covered was simple and quick. I had done some research at first and kinda knew what i was looking for. After talking with him, it affirmed my belief this was the right cover. Ordered on the phone and it was at my door in 8 days. Installation was simple. Took less than 2 hours to do by myself (it will simplify if you have a helping hand to put the cover on towards end of install). instructions were easy to follow and there are YouTube videos too. watch one before you begin and then just follow the instructions. Only had it on for a week or so at this point but its a great cover so far. 99% waterproof, provides decent security, SUPER low profile, high quality cover! all in all, very satisfied with cover and purchase. I'll be back!

2024 Ford Maverick bak revolver x4s

I ordered my hybrid Maverick xlt in 2022 and just got it 16 months later. The one good think about the 16 month wait is I read a lot about tonneau covers before I purchased the bak revolver x4s.
I first thought about buying a cheap cover for $2/300. But I figured I will own my truck for the next 10-15 years if not longer and I decided to buy the best and most secure cover on the market. I do keep some tools in my truck bed and my tailgate does have a lock on it.
This cover won’t keep a thief with a crowbar out of your bed but it will keep one out with a knife trying to cut their way in.
The cover is fantastic and I am very happy that I bought it.
It maybe over kill for others but for me it fits my needs perfectly.
It took me 30-45 minutes to install the cover with basic tools. It keeps the rain out but when I run my truck through a car wash , water does get forced in near the tail gate. So if you are looking for a completely waterproof cover I can’t say it is 100% waterproof. But again it doesn’t bother me.
I love the low profile and the quality of the cover. I expect it will last the lifetime of my truck. So for me that’s less than $70/80 bucks a year over 15 years. That comes out to .20 cents a day. I got an extra quarter a day to throw at the best cover on the market. You tube other people rating it and they will tell you the same thing.
Tonneau was fantastic to deal with!!
I placed my order and I think I had it delivered free to my house in 5-7 days. Their customer service is great . I contacted them wondering about the shipment and they got back to me right away.
Plus doesn’t charge sales tax so that was a discount over $80 vs Amazon .
Great company to deal with and I won’t hesitate to purchase from them again.
