This aluminum bumper gives you a higher weight rating so you can safely haul your bikes or generator to the campsite. You can store your smelly sewer hoses inside the bumper using the vented endcap to free up space in your compartment.


Features:

  • Bumper kit replaces your stock RV bumper for extra durability and a higher weight rating
    • Great for supporting cargo carriers, bike racks, and other bumper-mounted accessories
  • 10 Brackets reinforce the bumper to prevent heavy loads from damaging it
    • Less likely to lead to bumper detachment than a stock bumper with the same weight
  • Hollow compartment with vented end plates stores your wet, smelly sewer hoses and fittings
    • Circulates fresh air to prevent moisture and mold build-up
    • Slide the plates up and down to easily access your hoses
  • Rustproof, lightweight aluminum construction with glossy black finish
  • Bolt-on installation onto your RV's frame with included hardware - some drilling required
    • Need extension plates (MO24VR - sold separately) if frame is shorter than your RV's body
    • Need drop plates (MO84VR - sold separately) if your RV's body extends to the bottom of the frame
  • Made in the USA


Specs:

  • Application: I-beam, S-beam, tube, and channel frames
    • Flanged frames: must be at least 4" tall x 3" long
    • Non-flanged frames: must be at least 3" tall x 3" long
  • Overall bumper dimensions: 92" long x 4" wide x 4" tall
  • Maximum capacity: 550 lbs when evenly distributed
  • Weight: 22 lbs
  • Limited lifetime warranty


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.


Ventilated Storage Compartment


Mount-n-Lock Replacement RV Bumper Ventilated 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


Mount-n-Lock Replacement RV Bumpers 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.

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.

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.

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

Oh no! I am so sorry to hear that. Do you know the make and model of the bike rack you used?

@Edward It looks like the Mount-N-Lock hitch used, part # MNT47FR, was over loaded. The platform of the rack runs from sixteen inches to sixty six inches, putting the center of the load for the carrier platform at forty one inches out, or roughly three and a half feet. The rack itself is probably ninety percent of the one hundred eight pound carrier weight, or ninety seven pounds. So, ninety seven pounds times three and a half feet puts the empty carrier at three hundred forty pound feet, or forty pound feet greater than the rated capacity of the MNT47FR hitch...before the bikes are even added! Unfortunately, the hitch was simply overloaded. If there is a silver lining, at least your rack and bikes werent lost!

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!

Brackets need to curve up bumper scrapes when pulling into raised driveways etc.

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
