You get reinforced aluminum panels with a textured matte black finish, a 400 lb weight rating, and upgraded perimeter seals with an integrated drainage system. The G2 is the entry-level hard folding option — still a solid cover, but rated for 300 lbs and built with a more basic finish and sealing package. If you want the short version: G2 is budget-friendly, MX4 is the upgrade most buyers end up wanting.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eIs the MX4 waterproof?\u003c\/strong\u003e Water-resistant, not waterproof — and honestly, no folding tonneau on the market is truly waterproof. That said, the MX4 does a great job keeping the bed dry in normal driving and weather. It uses rubber perimeter seals, tight-fit clamps, and a built-in drainage system to channel water away from your cargo. For daily driving, car washes, and typical rain, you're covered.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCan I still use my tailgate normally?\u003c\/strong\u003e Yes. The cover is designed so your tailgate opens and closes as usual without touching the cover. No lifting, no unlatching — just drop the gate like you always would.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDoes the MX4 have a lock?\u003c\/strong\u003e There's no separate key lock on the cover itself. Instead, it uses automatic latching panels that secure when the tailgate is closed, so if your truck has a locking tailgate, your cargo is locked up the moment you lock the truck. Simple system, and it means one less key to carry.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow much weight can it hold?\u003c\/strong\u003e Up to 400 lbs evenly distributed across the closed cover. That's enough for tool bags, gear, camping equipment, or other everyday loads you'd want to keep on top when you're parked. Avoid concentrating heavy loads on a single spot.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCan I drive with the cover folded open?\u003c\/strong\u003e Yes. Fold the panels forward against the cab and they lock into place with the built-in prop rods, giving you full bed access on the road. Your third brake light stays visible in every position, so you're legal and safe to drive that way.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWill it fit my truck?\u003c\/strong\u003e The MX4 is made in application-specific sizes for each truck make, model, year, and bed length — it's not a universal cover. Run your truck through our fitment tool to confirm the right part number, or reach out to us directly and we'll verify the fit for you before you order.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow long does installation take?\u003c\/strong\u003e Plan on 30 to 60 minutes for a first-time install. No drilling and no special tools required on most trucks — the rails clamp directly to your bed, and the panels click into place. Most people can knock it out solo in a single session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BAK Industries","offers":[{"title":"Default Title","offer_id":52957856006443,"sku":null,"price":1049.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9148\/2923\/files\/imgi_113_gmc_mx4_1197x903_9270707b-d63f-4948-a484-308307fcc38a.jpg?v=1775725360","url":"https:\/\/truckbedbarn.com\/products\/bakflip-mx4-hard-folding-tonneau-cover","provider":"Truck Bed Barn","version":"1.0","type":"link"}
