ECOTRIC Universal Bumper Cargo Bracket fits RV 4" Square Bumper Mounting Mounted Cargo Carrier Box Support Arms Bracket Mounting Racks. (A Pair!)

Worked as advertised. Was plenty sturdy for the storage tub i mounted on my RV bumper.Didnt need to use the included bumper braces but was nice that they were included. As many commented no instruction included but installation was pretty straight forward.

**Update was able to add pictures mentioned**I wanted to be the first to review this product and include a few pictures to show what was included. I went out on a limb on the quality and what was included in this. The quality appears to be to be good, although i have not installed it yet. The black paint was applied well with no visible paint or metal flaws. It includes mounting hardware, carrier support arms, and bumper support brackets.The only thing im questioning is how im going to attache the bumper braces to my fully square camper frame. A quick hardware store run can fix this. No instructions as stated. Looks like everything is there to attach to most other frame types.I included lots of pics.RecapFinish: 10/10 - this "looks" very well made and producedItem includes what is needed: 7/10 - may have trouble with fully square/tube trailer frames with bumper bracesStructural quality: to be determined

4 stars because they throw in the bumper supports in addition to the cargo support arms which are okay but not great. If you're supporting a generator or something else heavy, either buy two sets of these or use another system. I went with a different cargo carrier that's rated to 500 lb but still installed these supports for added piece of mind. My carrier has a 2 inch tow receiver, welded to top of bumper, and the basket is only supported by the 2 inch tow bar (male end). It had more play than I cared for so these support arms were perfect for stabilizing each end.Why no instructions?? Seems ridiculous to me. The support arms are easy enough to figure out but still. The provided shim was not obvious and instructions would have helped. Instead, I assembled first then had to undo fasteners to install shim and re-fasten. Not much more work but doesn't help the fastener integrity.The bumper support installation is not rocket science but researching the installation of other similar products was a must. Maybe they should just provide instructions! As it turns out, I bought a separate set of bumper supports just in case the ones from this product were flimsy. I'd say they are comparable. Because I like piece of mind, I doubled up on my bumper support, sandwiching the I-beam between 2 brackets-maybe can see in picture. For installation tips see my review on the other product.Finally, as someone else said, not universally compatible with all cargo carriers. The predrilled holes did not align with my carrier so I had to drill new holes and buy different fasteners than what was provided. Still, I am satisfied with the product for my application.

I liked that it came with bolts and the reinforcement brackets for the rear bumper increasing the capacity of it to carry my generator. Since the arms were separate and could be spread apart as far or near as needed to make my custom generator carrier and cover to use for boondocking, it saved me time during my project. The only thing that would have been helpful would have been instructions, but it was pretty easy to figure out what needed to go where otherwise. For the time it saved me from not having to fab up some arms for the bumper I thought it was definitely worth the $48.90 I paid for it. Also, I like that they provided a weight capacity (200 lbs) so I could be sure my generator and custom tray all weighed far less than the rated capacity. I removed my spare tire and placed it in the cargo hold at the front of my trailer so I could install these brackets on the back and after adding to it all that I did it is just a little heavier than my spare tire/bracket was. Good Product and decent price.

Didn't come with any hardware. Just the metal brackets. Pictures seem to indicate the hardware is included, and all common reasoning would expect the nuts and bolts to be provided.

Awesome Bumper mount for light weight storage box.Total time to install on my KZ Sportsman bumper was less then 1/2 hour,, I di add cross bracing but awesome deal...

Super quick and easy to install, they also already have holes on the top platform to secure whatever you are sitting on top of it with the included bolts. Just need to potentially drill the storage box or platform you are setting on top of it.I used these for exactly the same example shown in the listing images - put a plastic storage box from Costco on top of it, use it to store items like beach toys, tire covers, wheel chocks, etc. - anything that otherwise gets dirty that I would rather not store inside the trailer's storage compartments. Also makes for much quicker/easier access to theses items.

Seems heavy duty. Says instalation instructions are included but they must have forgot to them in the one that was delivered to me cause there is nothing but brackets and bolts in the box.
