I added a generator on the back of my camper and started with a Arsken bumper mounted cargo carrier. The carrier is rated for 350 pounds but I knew as soon as I mounted it that it would never handle the weight of my 90 pound generator. These brackets made all the difference. I can stand on the cargo carrier with the generator and it is rock solid. It also helps by reducing the vibration when the generator is running. I would never consider mounting a generator without also adding these!

Easy assembly, fit well, very strong. Using it for my generator on our camper

This is a high quality product. Very simple to install. (About 20 minutes) The powder coating will assure that it will not rust.
Works perfect to take my generator on the go.

These along with installing bumper supports allowed me to install two lock boxes on the bumper of my rv.

It really got old lifting the genny in and out of the truck bed so I decided to find a way to avoid that. Saw these, and the bumper reinforcing Safety Struts, and decided to give them a try. Very easy to install the struts and the MnL arms. Had a couple of questions and the company responded in a timely manner with great advice. As I am ~180# of cargo I thought I might need an extra arm. After talking with the factory, who told me I could add an extra arm but it wasn't necessary, I finished the install in less than 30 minutes. I didn't buy the tray offered with this unit as I wanted one that was 24"x30" to accommodate the genny and 2 fuel cans. I made mine for about $75 and it is exactly what I wanted. I took the trailer on a 145 mile loop of Phoenix, AZ and the measurements were exactly the same after the trip as they were before. These products seem to be a great solution for the issues I had. Barring any future problems, which will get this review updated, at this point I highly recommend them.
