Planning on getting a brand new 4-bike rack and want to make sure your RV's bumper will be able to support the weight? Or perhaps you just need to replace the old, dented bumper that's currently on your rig? This durable, hefty bumper lets you upgrade the existing bumper on your RV so you can haul a cargo carrier, bike rack, or a spare tire carrier with confidence. And because the bumper is made out of aluminum, it won't rust in the rain or snow. The bumper has a bare, raw mill finish so you can paint it a color of your choosing.


Ventilated Storage Compartment

If you don't want to muck up the inside of your RV's cargo compartment, you can use the ventilated storage area inside the bumper to hide your smelly sewer hoses and fittings. When it's time to dump your back and gray tanks, slide the end plate up on either side of the bumper so you can easily grab your hoses. These end plates have small, built-in holes that help circulate fresh air to help prevent moisture and mold from building up on your wet hoses. And by keeping your sewer gear in the bumper, you'll free up space in your RV storage compartment for additional camping gear.


Bolt-On Installation

Once the old bumper has been removed, use the included hardware to directly mount this bumper onto your RV's frame. You may need to do some drilling. The bumper attaches with the included 10 brackets to provide additional reinforcement.


You may also need some Mount-n-Lock Addabumper plates. If your frame is shorter than your RV's body, some extension plates (MO24VR - sold separately) are required. And if your RV's body extends to the bottom of your frame, some drop plates (MO84VR - sold separately) are needed.

Video Transcript for Review of Mount-n-Lock RV Cargo Carrier - Replacement RV Bumper - MNT88VR

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Mount-n-Lock Heavy-Haul'r, 92-inch long, five and five sixteenths inch wide aluminum RV replacement bumper with the bare mill finish, has a 600 pound weight capacity. Now this bumper kit will let you add a bumper or even replace your stock RV bumper for extra durability and a higher weight rating. It is a heavy-duty aluminum bumper, so it does give you higher weight rating so that you can safely haul your bikes or generator to your campsite. It is also great for supporting cargo carriers and other bumper mounted accessories. One of those accessories we do sell is a two-inch hitch receiver that'll clamp around this bumper to give you a two-inch hitch receiver on the bumper.

This one will pop up an insert. There's what that part would look like. We do sell that separately on the website. It's part number MNT37FR, and it is listed on this product page as a related product, but as you can see on that insert, it clamps around here and gives you a two-inch hitch receiver opening. Now to install this, it uses 10 heavy duty brackets, five on each side.

There's five sandwiched together here, and then down here on the other side, there's five sandwiched together here. And these will attach to your vehicles frame right here and they'll reinforce the bumper to prevent any heavy loads from damaging it. So it's less likely to lead the bumper detachment than a stock bumper with the same weight. Now this bumper is a hollow compartment. If you see on each end, there's one on this end and one on the other end down there, they have these vented end plates that'll store and let you store your wet, smelly sewer hoses and fittings inside your bumper.

Those vent holes on here will allow fresh air to circulate prevent moisture and mold buildup. And the way you access to the inside you just slide open these plates. You can see this like that. Slide it to the side and it'll hold it open and you can put your sewer hoses, your fittings, anything in there, even when it's wet. Once you get 'em all in there to store 'em take your plate, drop it back down, and as we mentioned those vent holes will keep the air circulating in there.

Now this is a rustproof lightweight aluminum construction. This one has a bare mill finish to it. The bare mill finish can be painted to the color you want. This bumper is also available in a brushed finish. That'll be shiny. It hides scratches, but it does hold onto dirt since it is a rough surface. And then they also sell this with a nice glossy black powder coat mirror-like finish. We mentioned the bolt-on installation. It bolts to your RV's frame, comes with the included hardware right here. A nice set of instructions on how it all installs. There is some drilling required. Couple notes I do wanna mention. If your RV frame is shorter than your RV's body you will need extension plates, which we sell separately, part number MO24VR. Also, notice if your RV's body extends to the bottom of the frame, then you'll need drop plates, which are sold separately, part number MO84VR. This part is made in the USA. Specs again, this'll fit an I-beam, an S-beam, tube, and channel frames. Now if the frame is flanged, it must be at least four inches tall by three inches long. And if it's a non-flanged frame it must be at least three inches tall by three inches long. Few dimensions on this again, overall length from one end to the other end is 92 inches. The width is five and five sixteenths. Height is five and five sixteenths inches. Maximum capacity on this is 600 pounds when it's evenly distributed. And the weight on this bumper is about 40 pounds. But that should do it for the review on this Mount-n-Lock Heavy-Haul'r, 92-inch long, five and five sixteenths inch wide aluminum RV replacement bumper with the bare mill finish.

Satisfied & would by again. The original bumper on my 27-foot Freedom Express travel trailer failed when I mounted a lightweight bicycle rack on it. I replaced it with this Heavy-Haul'r bumper. This has worked well. No problem at all now carrying my bicycles. I also use it to carry a equipment rack with an auxiliary generator and gas can. I usually run the generator from the carry rack attached to the Heavy-Haul'r bumper. A bit slow installing with some frame drilling on my camper required but works great once installed.

Product quality is very good and powder coating was well done. My issue is with the shipment packaging. Although there was an attempt to protect the product in transit it did in fact fail. I recommend the shipper place reinforced cardboard on all four corners from top to bottom and also add reinforced cardboard at each end of the bumper. The shrink wrap was an attempt but didn’t prevent the scratches and dents. After spending nearly $[XX] for the bumper I would say an additional $[XX] spent in proper packaging would eliminate any returns. See pictures.

This is an impressive bumper. We ordered this to be delivered to a RV park in FL after our original 4” bumper twisted & broke the welds on our trip down from the weight of our mountain bikes (~ 200 lb total).
We went with a 5.3” replacement to make it easier to insert our sewer hoses & adapters. My husband & neighbor put the new bumper on in 2 h; it did require drilling new holes in the frame but that was easy enough & well worth it. This bumper is exceptionally strong, has a great finish and has a much better solution for closing the ends than your typical end caps. We also bought the 2” Shake-Stopper Hitch Receiver and it mounted in about 20 min. It is super strong and as advertised - it makes a very solid connection with the bumper. Highly recommend both

Heavy duty quality metal. Came well packaged. Great instructions with photos. Clever engineering.

Love the product and the ability to safely handle more cargo such as our 4 bike carrier. My only qualm is if you have a Camco Rhino waste hose you will have to use your old end cover instead of the stock ends that come with the unit. The little screws that hold the metal pieces in place are in the way and the hose will not go in.



by:

Both products failed with a 4-bike rack rated for RV use the first time I used it.



by:

The products I bought came a little earlier than originally stated, and that was great. Unpacking the products was a big pain in the a. However, every thing was in good shape. My main complaint that gives the 4 stars is I ordered a 4 inch bumper to replace my old 4 inch bumper, but with the slide gates on the ends (which looked like a great idea) my 4 inch dump hose won't slide in past the slide gates. Customer service says I'd have to have a 3 inch hose or buy a bigger bumper. That was not an issue I saw while shopping for the bumper. In fact, the little video showed tipping the slide gate to the side and easily sliding the hose inside. Nope! It never said anything about a smaller hose. I'm going to have to take off the screw in the slide gate on one end of the bumper and remove the gate every time I want my hose. I hope it won't bounce out while I am traveling. If it does I'll go back to a rubber cap, rats!

  • Replacement Bumper for Generator and Cargo Carrier on Grey Wolf Black Label
    Hi David; all of our heavy duty bumpers like the # MNT88VR you were looking at have the same fitment since it is designed to be universal. However, you will need to check out the frame on your Grey Wolf Black Label to make sure it is compatible. This fits I-beam, S-beam, tube, and channel frames which covers almost everything. If you have a flanged frame it must be at least 4" tall x 3" long and non-flanged frames must be 3" tall x 3" long. If your frame is shorter than your RV body you...
