Great product very easy to install. I do mobile reconditioning on cars and needed to get the generator out of the trailer without breaking my back moving in and out everyday.



by:

Great customer service. Received within two days. Good quality and exactly what I needed and ordered. I’m using as a slide for a toolbox. I have order before from etrailer, and will order again.



by:

Great slide! Works exactly as expected



by:

Love this slide out tray. Bought it for a generator it has worked perfectly and handles the weight



by:

Great generator slider, easy to install and holds the weight of my 100lbs predator generator no problem



by:

The generator slider is nice. It has a lock to keep it in the trailer. But nothing to hold the generator out when you’re using it. When generator is running it moves the slider back on. It needs to have a lock to keep the generator out of the trailer.



by:

Fits perfectly and works just like I ho ped.

Looks great, Nino! I bet it makes it easier to access the generator too :D



by:

Overall condition of tray was received good… the slide of the tray is not as smooth as I would have liked… after putting on a little silicone spray is appears to be better.
Also, there was no mounting hardware included in the package… had to use my own bolts & nuts to secure to my bay floor.



by:

This is the perfect solution to my issue with having to load and unload my generator by myself. I can now safely run my generator with the slide pulled all the way out. The quality is excellent and very well put together.



by:

SUPER FAST shipping, exactly what I needed. ::high five:: thank you! Our generator was side swiped and the tray was the only part damaged. You guys had exactly what we needed and I got it so fast that we didn't miss a day of ice cream for doggies! Now my busted generator tray is back to pristine and perfect.



by:

I installed my Predator 9500 generator on it. I had to remove the wheels but it works perfectly.



by:

We actually purchased these for two fire engines to hold our ice chest that we have on the engines. They were a perfect fit in our side compartments that allows us to access the cooler via the pull-out trays without having to take the coolers office the engines. The pull outs also make it much easier draining and refilling with water and sports drinks for the firefighters.



by:

This generator slide out was exactly what I was looking for. My wife had bought a new generator for my race car trailer so now was the time to upgrade. The MORryde generator slide out is very heavy and seems very well built. Slides out and back in easily. The only thing that I would change is the length of straps that came with it. But that is really a non issue as I wasn’t buying this for the straps. It does not come with hardware to bolt it down but this is stated in the description. Each installation is different so again this is not an issue. Very pleased with the product and would recommend this to anyone.



by:

Missing instructions or hardware just the shelf came



by:

I purchased the Morryde generator tray for my Yamaha generator. The tray was easy to install in front compartment of 5th wheel rv. The tray easily handles the 150 lb generator and there's enough clearances to access all components of generator including changing oil.



by:

Thanks for keeping my informed as to my order status. I received the MORryde RV Generator Slide Out Tray - 25-3/4" x 26-1/4" in perfect condition. The weight of the item is 52 lbs. and is well built. It will be perfect for my Portable Onan 4500i Generator, which ways about 100 lbs. I haven't installed the tray yet, but it will work out perfect in the rear storage compartment on my 5th Wheel Trailer.



by:

Great product. Got it installed in my van this week and I love it. My only issue was ordering the incorrect size unit for my generator. I went off of the dimensions on the description of the product from the first page of spec sheet. Those weee actually the overall size specs, including slide rails.

The beautiful part about that was the customer service and response from etrailer. They took the product back, even after I installed it, paid for the freight back with no restocking fee, and sent me the correct unit for my generator. I paid the difference in price and they chose the fastest possible freight option to get it to me.

Awesome experience and I will find a way to do business with etrailer again.



by:

I am unsure if I received a faulty product. I am using a 3500 Predator generator for my detailing setup, and the pull out does not stay pulled out unless the ground is slanted. I would of thought I locked in place. Also this set up does not bring the screws or proper hardware.

I can see where that would be a bit troublesome. I reached out to MORryde about it. This tray does not have a lock in the out position. They had had people add blocking or a lock on their own to allow the generator to stay in place. I wish that I had an official solution to recommend for you.



by:

Works great for predator 5000, little extra space as well



by:

These trays are awesome. I've purchased three so far for generators in our mobile detailing vans. Oldest one is two years old with and gets used daily. Haven't had any issues. Will definitely be buying more as we grow!

Hey Kyle! I love to hear that your business is growing! I can't wait to see how your business grows, we will always be there for ya.



by:

This tray is perfect for the generator box I am building for my race trailer. Also, despite its size and weight, this was delivered the day after I ordered it without any extra cost. Nice product and great service.



by:

Great quality and fits a predator 5000 perfectly. Great for a detailing set up!

That’s a great setup, I love it. That Predator 5000 looks like it was made for that tray. Being able to just slide the generator out instead of wrestling with it is such a game changer, especially when you’re busy detailing cars. That’s a pretty awesome mobile setup you’ve got going. What kind of detailing work do you usually do?



by:

So far, I’ve used this slide out for a 5000 W generator out of the back of my detailing van. The generator weighs 110lbs without fuel so it’s being used quite often with about 150 pounds total being slammed in and out of the van multiple times a day. It’s still as smooth as the day I bought it and installed it. I use harsh chemicals all the time and the finish is even holding up very well. I could not be more impressed and I would absolutely recommend this slide out for anyone that needs that absolute reliability every single time!



by:

We bought the slide out tray specifically for our generator, which is a predator 3500. It has worked to our expectations and highly recommend it.

Still working well…would definitely recommend

I am using for a battery slide out as I recently switched to LiFePo batteries. This has worked great for this application as it is very robust, the dimensions were perfect and had excellent weight capacity.

Glad it's working well for you, Michoel! Good idea using it for your batteries as well. Will definitely make it easier to access them when you need to. ^___^ What did you install this in?
