Tie-down Points

Tie-down Points

Whether you're hauling a small suitcase, large 100 lb generator, or gear for a weekend camping trip, this dynamic cargo carrier tray has over 60 different tie-down points (tie-down straps sold separately) to strap down your cargo from any angle, giving you the security you want traveling on bumpy gravel roads, or flying down the highway over long distances.


Expandable Design

Expandable Design

This highly versatile, expandable design allows you to lengthen your cargo-carrying platform from 2' all the way up to 8' (additional trays and support arms sold separately). You can safely haul and store multiple generators or propane tanks on one side and all your camping gear and coolers on the other side.


3 Different Assembly Options


Compact assembly mounts your cargo tray over your bumper to bring your tray 5" closer, giving you more strength to haul heavy generators, propane tanks, or bundles of firewood. This setup will also provide additional clearance space around your RV.


Standard assembly mounts your cargo tray just off your bumper to accommodate RVs where the body overhangs the bumper. This setup allows you to invert your side rails to combine trays and expand your platform up to 8' (additional trays and support arms sold separately) or to hook up a ramp to load your bike.


Extended assembly frees up an additional 5" of space between the back of the tray and your RV to allow a longer cooler or camping chair to overhang your bumper. This setup allows you to invert your side rails to combine trays and expand your platform up to 8' (additional trays and support arms sold separately) or to hook up a ramp to load your bike.

Exceptional customer service. The product is well made, easy to assemble, sturdy and attractive.

Looks great



by:

Still need to install. Just what I have been looking for.



by:

Works great haven't any problems even on rough rdd



by:

Great way to add some extra storage to a RV; in my case a new generator. Solid construction and easy assembly as well. I think the aluminum on top of steel beams (where the stability is needed) adds “some color” too. I opted for the sturdier on top of the bumper installation as I only needed the given 24x24” space of the single try design I ordered.



by:

This cargo carrier is exactly what I was looking for. After checking that my trailer bumper was rated for what I wanted to use this cargo carrier for I pulled the trigger and made the purchase. My order shipped quickly and arrived in the time specified. Assembly and mounting were easy enough once I puzzled out the included instruction card. Some mentioned that the assembly instructions are inadequate, there is a web address for the same instruction card but also on that page is a video that will give you some helpful hints though not thorough since that video doesn't show how to assemble the mounting brackets. However, with a little patience puzzling over the included instructions you will figure it out quick enough. I certainly didn't spend more then 30 or 40 minutes getting my GennyGo mounted and assembled. Sorry I didn't take any photos of my process. Anyway, this 24"X24" 200lbs capacity carrier is perfect for what I wanted - A way to carry my generator without having to load it in the bed of my pickup with our bikes. With this cargo carrier I can secure and lock my generator to the carrier and it's ready to go when we pull into our campground.

Was very pleased with the generator car rier.

Well made and easy to put together!



by:

I have not installed it yet, but I have put it together and everything looks perfect.

I was at first surprised at the diminutive size of the box - but it soon became clear - the utter genius in the design of this product. The tray comes in 4 triangular pieces that allow for a variety of set-ups. I purchased the hybrid model aluminum tray and steel support arms. There were a couple of things in the instructions that seemed vague, but a second and third looked confirmed the instruction (this mainly had to do with the attaching of the steel support arms and extension option - as always one should look through the instructions BEFORE beginning the task). Once assemble everything fit like perfectly and was a breeze to install. Also purchased Item #MO34VR support struts. That product proved to be much more work than the tray, but did work out nicely and is a HUGE peace of mind product, totally worth the work and the price. I have a 24' Jayco Jayflight SLX with a 4" square bumper. After drilling through the frame I can assure you you'll need the struts. Yes the bumper joints are welded solid but the metal is not nearly as thick as it may appear. Thinking "this is gonna take all day", a few seconds after starting the drill on the frame, I was through the other side. Buy the struts if you have a comparable rig.



by:

Great product, stronger than I anticipated. Fairly easy to assemble. I did have to cut the support arm ends where they go over the bumper so they didn't hit the trailer cab,no big deal.
Happy with my purchase.



by:

Great sturdy product



by:

It’s a nice cargo trailer but it’s too small so it don’t get to use it



by:

Took my 86 lb generator acrossed the country. Did exactly what they said. I love the multiple tie down spots, makes it easy to fasten down my geni and keep it tight.would recommend this product to everyone.



by:

Arrived a day late but in good condition



by:

Normally I'm not one to leave negative reviews, but you guys sent me an email so here I am.

To be blunt, I get where they were going with this design but it's not nearly sturdy enough. My generator weighs 134 lb and is a little propane 3000W. It didn't matter how much I tightened to the clamp bolts, this thing was not even close to strong enough to hold the generator. The platform seems like it was acceptably strong, but the means of mounting the platform was terrible. I tried to adapt it with some stronger u bolts but the little struts under the platform couldn't quite handle it either. The metal was thin enough that even with 1 in washers, it's slowly began bending.

After about 2000 miles of stopping every couple hours and screwing with it, I just took it off and threw it away.



by:

Was not what i expected very thin aluminum and the brackets seem very under rated I have a 100lb generator and the directions say this product is rated for 200 lbs



by:

Easy to mount, very sturdy. I’ve used it to carry my two Honda generators, or if I know I have power, my portable Traeger and pellets.



by:

Item arrived on time and components of good quality. The only reason I'm returning 4 stars and not 5 is the abysmal instructions and diagrams - kind of a suck it and see exercise, but other than that, very pleased.



by:

Your product looks like it would do the job nicely. My trailer bumper is another story. It is so lightweight i’m sure it would rip right off and my honda generator would be a gonner for sure. The cost to have a reinforced bumper made would buy a new lighter generator , that would solve my original problem



by:

Works great. Carry my generator on back of camper. Just took a long road trip hit some rough roads at high speed held up great



by:

Purchased this product to hold my generac 3000i generator. Was the perfect size and had enough holes to adequately strap down the generator and gas tank



by:

Easy to install. Just make sure you get the right bolts and nuts for the brackets and not use the tray ones. I carry my small 30 amp generator one it.



by:

We were not expecting the vibration when our generator was running. The entire trailer rattled and couldn't wait to turn it off.



by:

With the addition of Mount-n-Lock SafetyStruts Standard RV Bumper Support Brackets - 4" to 4-1/2," it securely holds Predator 3500 generator on the bumper of my travel trailer.

  • Correct Mount-n-Lock SafetyStruts for 2022 Grand Design Transcend Xplor 321BH
    The answer to your question will depend on your bumper. More than likely the # MO22FR will be the correct part for your Grand Design Transcend Xplor 321BH. If you have a tube frame with a bumper that is 4" - 4-1/2" wide then this will work as extra support for your carrier and generator. You can see this in the attached review video at the 2 minute mark. If you have an I-beam, S-beam, or single channel frame you want the universal # MO34VR instead.

He said not to use just the Replacement Support Arms for Mount-n-Lock GennyGo Generator and Cargo Carrier item # MNT84FR to support a generator. These arms can be used to upgrade a current systems capacity but they are not rated to be used without the tray.

    While a front mount cargo carrier that attaches to Blue Ox base plates is not offered, we do have a solution for you to install a cargo carrier, but it needs to be on the back of your Jeep or mounted to the top. Using the rear mounted hitch, you can install a carrier such as the etrailer # e98874.

  • Can the Mount-n-Lock GennyGo Generator and Cargo Carrier be Installed on a Trailer Tongue
    I guess if your trailer tongue is 4", 4-1/2", or 6" squared then the Mount-n-Lock GennyGo Generator and Cargo Carrier # MNT77FR could technically fit, but this was designed and tested for being installed on the bumper of an RV. If you were to install this on a trailer tongue then your load would be putting force perpendicular to the brackets as opposed to in line. Since this wasn't tested in this manner I only recommend using this on the bumper of your RV. The only kind of tray that we...
