BAK MX4 2023 ram 1500

This is my third MX4 tonneau cover over the years . They look as good as they function. While the emails from can be slightly annoying they have the best pricing and the customer service keeps you well informed.

Personal service and good product

Order came within 4 days and had no damage.
Installation instructions were not the best however I am very happy with the product.

BAKflip MX4

After searching and reviewing a lot of different covers I decided to go with the MX4 - best decision ever. Super easy install - only took about 45 mins by myself- everything was included with step by step directions. Great fit and I can still haul my ATV in the bed of my truck with this cover. Very happy with the quality and durability.

Very nice product
