Features to know about

Park Fifth Wheels and Standard Trailers with Wireless Freedom


Transformer triptych in use

Imagine guiding your trailer into a tight driveway or winding through rows of a busy storage lot, all while walking beside it with the wireless joystick in your hand. With adapters for both king pin and ball couplers, you can connect to most fifth wheels or standard trailers with confidence. You get a clear view of every angle, can spot obstacles before they become problems, and move your trailer with less stress, even if you're working solo. When you're ready to move the dolly by itself, just switch to the free spool setting. This makes it easy to roll the unit by hand, so you can position it exactly where you want, even in a crowded garage or storage area.

Adaptable Connection for a Wide Range of Trailers


King pin adapter in use

Move more than one kind of trailer without needing a second dolly. The king pin adapter, paired with stabilizer bars, creates a solid and secure connection for standard frame fifth wheel trailers. When you need to switch to a bumper pull, use the 20" ball mount for any 2" or 2-5/16" coupler. You can also connect using a standard round trailer jack post by sliding it into the dolly's receiver tube, giving you another simple attachment option. Changing from a 5th wheel setup to the hitch ball involves removing the stabilizer bars and swapping adapters, so allow a bit of extra time for the transition.

Stay in Control with Brakes and Visibility Built In

Park trailers safely on firm surfaces like asphalt, grass, or packed gravel. It can handle slight slopes up to a 4% grade, giving you more flexibility in real-world parking situations. The wide tires help keep you steady as you guide your trailer into place, no matter if you are working in your own driveway or managing a busy storage lot. Plug in the 7-way cord and the trailer brakes and lights come on automatically, giving you better control and visibility even after sunset. This dolly works with standard electric and surge brake systems, giving you consistent stopping power across a wide range of trailers. Electric-over-hydraulic systems require a custom brake plug, which is not included.

Controlled Movement for Heavy Loads


Transformer controller

Move 5th wheels up to 15,000 lbs and trailers up to 10,000 lbs across firm, level ground at the speed you need. Switch between high and low speed for careful positioning or quicker moves when space allows. The dolly slows to a gentle stop after you release the control, which helps protect what your towing from sudden jolts. With a strong steel frame, a powerful electric motor, and easy variable speed, parking, hitching, and repositioning are more manageable, even in tight areas or busy lots.

Easy Charging and Simple Setup


Transformer feature 5

Keep your dolly ready for action with the included rechargeable 12V batteries and charging cable, and recharge the wireless remote using the included USB-C cable. The built-in voltmeter lets you check your power level before you get started, and the push-button battery disconnect makes it easy to conserve power when not in use. The dolly arrives fully assembled, so after a quick battery top-off, you can start moving your trailer right away. Setup is straightforward and you spend less time getting ready and more time parking trailers at home or on the job.

Love it, worked on our 13k weight trailer without a problem. The remote control option is sweet too!

Works great. Instructions could be written better.

Takes what was a 45 minute fight to a 15 minute job

This is a very good trailer dolly on flat ground. However, it lost traction easily on a slope.



by:

Works great on my boat trailer and my fifth wheel. Doesn't work well for my truck camper dolly due to lack of tongue weight. I literally have to sit on the box while the wheels struggle to make traction on my concrete driveway (which is less than 1 degree, I live in South Florida) Oh well, it is worth it just to back my 40' fifth wheel up the driveway and into the yard so I consider that a win! Good price (I bought the scratch and dent) and apparently before the next big price increase. I love the fact it came assembled with batteries charged and all I had to do was drive it off the pallet and that it was ready to use. Also loved all the instructional information from the vendor, etrailer, and the interwebs at large. I plan to continue using etrailer as a primary source of stuff I need.

  • Recommended Electric Trailer Dolly That Works on Gravel w/ a 6,000 lbs Travel Trailer
    Hey Brian. The Trailer Valet RVR3 item # TVRVR3-BB225, you were looking at, is actually smaller than your Trailer Valet RVR5 item # TVRVR5. It's going to do even worse job on gravel plus it's way under-capacity for your 2023 Airstream Flying Cloud 23FBT. The Parkit360 Transformer Electric Trailer Dolly item # PA66VR also works with travel trailers and it is going to be your best option. It has a 10,000 lbs capacity and the large rear tires work great on gravel. We played around with one...

  • Can Parkit360 Transformer PA66VR Work For 2,000 lb Pin Weight On Packed Gravel?
    Hello Eric, thanks for reaching out. On packed gravel, yes, the Parkit360 Transformer Electric Trailer Dolly # PA66VR can work great, but with the weight of your camper, and the Gen-Y goosebox, no this is not recommended. You would need to use the gooseneck/ball mount adapter and this is only rated for 1,000 lbs of tongue weight. With your trailer being around 2K tongue weight you would be way over the weight capacity so it would not be safe.

  • Which Parkit360 Electric Trailer Dolly Can Move My Boat Trailer Over Wet Grass?
    Hi Tim! You can use the trailer dolly Force # PA96VR on firm, dry grass, but traction will drop off if the ground’s soft or damp. Since it’s a single-motor design, a little extra tongue weight helps the drive tire bite in better. If you’ll be moving on grass or uneven ground regularly, the Parkit360 Transformer # PA66VR is worth a look. It uses dual 1.7-horsepower motors and stabilizer bars to keep both tires driving evenly, so it maintains traction better on slopes or softer surfaces...

  • Will Electric Trailer Dolly Work On Boat Trailer Surge Brakes Or Will It Lock Up When Backing Up?
    That’s a great question John, and one a lot of folks run into. The Parkit360 dollies like 5K # PA96VR and 10K # PA66VR can absolutely move a trailer with surge brakes, but you’ll need to keep the actuator from engaging in reverse. The dolly’s 7-way Smart Brake plug doesn’t connect to a surge coupler unless you adapt it. If your trailer uses a 5-flat plug, you can pair the dolly with a Mighty Cord 7-Way RV Style to 5-Way Flat Trailer Connector Adapter # A10-7275VP. That lets the dolly send...

  • Availability of Parkit360 Rated for 15,000 lbs
    Hey Carter! We do have the 15k model of the Parkit360. That would be the Parkit360 Transformer Trailer Dolly # PA66VR. This includes the king pin adapter that will allow you to move a 5th wheel up to 15,000 lbs. What kind of 5th wheel do you have?

  • Will The Electric Trailer Dolly From Parkit360 Work On Gravel Or Will Tires Spin?
    Brian, good question. The Force dolly 5K lbs # PA96VR performs best on paved or packed gravel. If your gravel is loose or deep, the narrow drive tires can dig in, but a few wood boards under the trailer wheels usually solve that. For frequent off-pavement use, the bigger Transformer # PA66VR has heavier duty build with 4 wheels/tires and a dual-motor setup that’s a bit more forgiving on uneven ground. Is your trailer single- or dual-axle? That can make a big difference in how tight you...

  • Comparing Which Electric Trailer Dolly To Use For 10,000lb Enclosed Trailer
    Good morning, Trevor. If your trailer’s right at 10,000 lbs, go with the Transformer # PA66VR. It’s rated for 15K and uses dual motors and stabilizer bars, so it keeps traction a lot better when turning or on gravel. The Force # PA96VR is great up to 5K and will struggle with that much load or tongue weight. Both use the same 6-1/2inch drive tires and Smart Brake plug, but the Transformer gives you wireless control and way more torque, along with the option to pull 5th wheel and gooseneck...

  • Availbility of Trailer Dolly for 2022 Escape 5.0 5th Wheel
    Hey Thomas! The Parkit360 Transformer Trailer Dolly # PA66VR is the option we have for your 2022 Escape 5.0 fifth wheel. It includes a kingpin adapter that attaches directly to the king pin along with stabilizer bars to keep the dolly secure while you're moving the trailer. The Transformer is rated for fifth wheels up to 15,000 lbs with a maximum pin weight of 3,000 lbs, so it has more than enough capacity for your Escape 5.0. What kind of surface will you be moving the trailer on?

  • Difficulty Turning w/ the Parkit360 Force Electric Trailer Dolly
    Hey Terry. The Parkit360 Force Electric Trailer Dolly item # PA46VR does not have turning wheels and those larger, 6-1/2" wide tires, are not going to turn on a dime. You'll have to do some maneuvering with it to pull off a sharp turn. The Parkit360 Transformer Electric Trailer Dolly with Kingpin and Hitch Adapter item # PA66VR has turning wheels and you can go in circles with this one. The cost is quite a bit higher for the better turning radius though. What kind of trailer do you have?

  • What is the Maximum Incline for Parkit360 Carrier and Parkit360 Transformer Electric Trailer Dolly
    Hey Logan! The Parkit360 Carrier Electric Trailer Dolly # PA76VR actually has two different ratings. If the trailer is 10,000 lbs or less it is limited to a 6% grade and if it is over 10,000 lbs it is a 4% grade. The Parkit360 Transformer Electric Trailer Dolly # PA66VR is limited to a 4% grade no matter what the trailer weighs. What kind of trailers do you have? Let me know if you have any other questions.

  • How Do I Install The Parkit360 Transformer Stabilizer Bars If I have Hydraulic Jack Legs
    That's a really good question, Dan! For this type of set up you would need to attach the Parkit360 Transformer, part # PA66VR, stabilizer bars to the kingpin box instead. I've gone ahead and included attachments that show step by step how to do that as well as a snip from one of Parkit's video they have online. I'll go ahead and include the steps below as well for ya. - OUTER PIVOT TUBES Install both 1 1/2” Outer Pivot Tubes to the wings of the Mounting Ring Tube. Thread 2 1/2" x 1/2”...

  • Can Parkit360 Transformer Electric Trailer Dolly Move 10,000lb Car Hauler Up 3 Degree Slope?
    Aaron, good question - the Transformer # PA66VR is rated for slopes up to about a 4% grade, which translates to roughly 2–2.5 degrees of slope. Since your driveway measures around 3 degrees (about 5%), that’s just above the safe operating range. It might still work for short moves if the surface is smooth and you go slow in low-speed mode, but Parkit360 officially recommends keeping it under that 4% slope limit to prevent runaway load risk. The built-in Smart Brake system will hold your...

  • Do You have a Parkit360 Trailer Dolly that will Move a 5th Wheel?
    Hello Tareq, Great question! The Parkit360 Carrier Electric Trailer Dolly - Wireless Controller - 13,000 lbs # PA76VR is designed to work with trailers that have a standard coupler, so it would not be compatible with a 5th wheel, there is not an attachment for it. For a 5th wheel, you will want the Parkit360 Transformer Electric Trailer Dolly with Kingpin and Hitch Adapter - Wireless # PA66VR. This model includes the kingpin attachment needed for 5th wheels and is rated for trailers...

  • How To Move 40' 5th Wheel Trailer 13,000lbs Around Parking Lot For Storage And Maintenance?
    Hey Dave. Yes, that’s exactly what the Transformer # PA66VR is built for. It’s rated for trailers up to 15,000 lbs GVWR and 3,000 lbs tongue weight, so you’re well within limits. The dual 1.7-horsepower motors and stabilizer bars keep both drive tires planted evenly for steady traction even under heavy pin loads. Just make sure you’re on level ground 4 grade max and that the stabilizer bars are fully installed before moving. Do you usually store your fifth wheel on pavement or packed gravel?...

  • What Is The Run Time Before Needing To Charge The Parkit360 Transformer 15K Trailer Dolly?
    Cheryl, each Transformer dolly # PA66VR includes two 12-volt Interstate U1 deep-cycle batteries wired in parallel (12V, 2x the amperage). You’ll typically get around 30–40 minutes of continuous operation on a full charge - more than enough to maneuver several large trailers. The on-board charger plugs straight into a wall outlet, and you can check battery voltage on the built-in display. Parkit360 recommends topping off every couple months in storage to maximize lifespan. Do you plan to...

    You sure can, Laura. The wireless controller for the # PA66VR has dual joysticks that let you steer each drive motor independently - perfect for inching into tight storage spots. It works at a range of up to 40 feet, so you can walk alongside or behind the trailer for full visibility. There’s even a high and low speed toggle built in, giving you precise, gradual control on delicate surfaces like pavers or concrete pads. The controller can also be placed in the holder on the handlebars...

  • Is there a Gooseneck Adapter for the Parkit360 Transformer Trailer Dolly?
    Hi Robert, On Parkit360's website, they say that the Transformer 15K-G model trailer dolly can be used to move gooseneck trailers. However, they say to call and tell them the trailer's dimensions before ordering so the dolly can be made to your gooseneck trailer's dimensions. I couldn't find any adapters to use the Transformer part # PA66VR so it must need to be custom made by them to work with the trailer dolly and your gooseneck trailer. What kind of terrain are you wanting to use...

  • Will Transformer Electric Dolly Connect To 5th Wheel Kingpin?
    Kevin, the # PA66VR will work for that. You’ll just attach the included Kingpin Adapter, which clamps directly onto your trailer’s kingpin without modification. It locks in place using a supplied U-pin and D-clip, then slides right into the dolly’s receiver tube. Once you’ve installed the universal stabilizer bars between the dolly and the trailer frame, you’re ready to roll. Setup takes about 10–15 minutes the first time, then it’s tool-free after that. What do you currently do to maneuver...

  • What Kind Of Maintenance Does The Transformer Electric Trailer Dolly Require?
    Steve, the trailer dolly # PA66VR needs very little maintenance - just a few preventive steps. Grease the wheel fittings and flange bearings once a year, keep the chain lubricated, and charge the onboard batteries every month or two when not in use. It’s also a good idea to keep the receiver tube and ball mount collar lightly greased for easier coupling. The whole system’s designed for longevity - the motor circuits even have resettable breakers to protect against overloads. I have personally...
