Fits All Trailers

This is the greatest aspect about this model – if you own multiple trailers, it will park them all -, and there’s no issue if you decide to trade your old caravan for a new one, as it will most probably adapt to it as well. This is the advantage that comes with a high-quality model that comes with the following specifications:

  • 10,000-lb weight capacity – it can easily deal with heavy trailers without overloading. It also has a great 900-lb. tongue weight capacity, which means that you can hook a fully-loaded trailer, and it will be able to steer smoothly on most surfaces.

The kit also comprises all the hardware you will need to connect the dolly to your trailer, counting an Allen key and 2 screw sets.

Intelligent Speed Control

One thing most trailer owners fear is that they may lose control over their vehicle while moving it. Well, this is basically impossible with the Parkit360 10K B3, which comes with an intelligent braking system.

  • Battery level monitoring – not only that the battery is included, along with a charger to help you keep it full, but this system integrates a voltmeter with a battery level reading function, which will tell you how much power is left, so you know when it is time to recharge the battery. In general, a full battery will last for 1.5 to 2 hours of continuous use.

This system weighs about 109 lbs. with the battery mounted, so it is fairly lightweight. It is well packed together as well, so it is easy to store inside the trailer. For any manufacturing flaws that may interfere with its operation, the manufacturer offers a 2-year warranty.

If you are using a solar system to power your devices and appliances during your trips, you need a device that can regulate voltage and ensure that the current that is transmitted from the panels to the batteries doesn’t damage the latter. We recommend investing in a solar charge controller, which will allow you to monitor your system and make sure it is operating optimally.

The frame is made from steel, so super reliable, as long as the 3,600-lb. weight capacity isn’t surpassed. With a high-quality powder coat, it is bound to resist humid weather, but make a note that it is not waterproof, so you shouldn’t expose it directly to water.

Furthermore, the size of the wheels is one of the largest, so you can expect more stability and better control.

It’s always wise to keep a generator at hand for those moments you may not get access to AC power. While there are plenty of fuel-based models on the market, nothing compares with the advantage of getting free energy, which is only offered by a portable solar generator kit, so make sure you add one to your trailer before hitting the road.

Buying Guide

These products come with adaptable hitch connection mechanisms that make them suitable for almost all campers or boats. Nevertheless, if a dolly fits your trailer, it doesn’t necessarily mean that it can move it in any conditions, so it is always advised to compare the mover’s specifications to the ones your trailer has to make sure you don’t end up with a product that cannot handle it.

In this direction, we’ve put together a short checklist you can use to select the most fitting product.

  • Maximum weight capacity – you need that the trailer’s gross weight corresponds to the dolly’s transportation capacity. If the value is equal to the manufacturer’s specification or lower, you are safe to purchase the model, but if the value is higher, you need to look into a more powerful option.
  • Maximum tongue weight capacity – this is usually 10% to 15% from the camper’s gross weight, and it represents the maximum pressure a loaded trailer can exert on the hitch ball of the dolly. If this value is higher than the one recommended by the manufacturer, the trailer may end up damaging your mover.
  • Construction – you want the product you buy to live as long as possible, so check that the frame is built from a time-resistant material like aluminum or steel, and even more importantly, that it is powder coated so rust cannot find its way into the metal. Check that the frame is thick and the parts are well-crafted.
  • Hitch connection compatibility – in most cases, you won’t find problems fitting any dolly to your trailer, but exceptions exist. If you notice that the dolly’s hitch connection system is not working for your vehicle, check if you can buy an adapter. If not, it’s time to move to another model.

  • Brakes – the braking system is super important, as all it takes is a moment of distraction for your camper to go rolling uncontrollably and get damaged or even hurt someone. Most models in our top have automatic brakes, and some even come with intelligent braking systems that ensure soft starts and stops to prevent damage from being done to the vehicle. On the other hand, you may find some products that don’t include a braking system but accept one that needs to be purchased separately.
  • Terrain compatibility – you need to look at the wheels and consider that larger models with thick tires are usually more efficient on soft ground. Another thing that interests is if your driveway presents a slope, as the dolly must be able to climb it. Most models in this top will deal with inclines from 4 to 6 degrees.
  • Warranty – last but not least, if the product comes with a long service contract, this is a good sign that your option is well-built. Make sure to check if the company provides a phone number or an e-mail address, so you can easily get in touch with them in case the product you receive doesn’t function optimally.

What is the best motorized trailer dolly?
Parkit360 10K B3 has an excellent weight capacity of 10,000 lbs. that can hardly be equaled by other movers. It comes with an intelligent braking system that ensures the unit has both a soft start and stop so the trailer doesn’t get damaged in the process. With a steel construction and all-terrain wheels, this is the best electric dolly of the moment.

Is a trailer dolly worth it?
Yes. If trying to fit your trailer into a parking lot manually or by using your vehicle is your idea of vacation parking, then maybe you don’t need one, but if you care about your comfort, a mover will definitely make things easier. To put it short, this mechanism attaches to your trailer and uses an electric motor to move it. There’s no pushing or pulling required on your part. You just need to control the system either through a remote control or a set of buttons that are placed on the mover’s handle.

What is tongue weight?
The tongue weight represents the load a fully loaded trailer exerts on the hitch ball. Thus, the tongue weight capacity measures the maximum weight the hitch ball can support without breaking. In general, the tongue weight is 10% of the gross trailer weight. It is indicated that you never hook a trailer with a higher tongue weight than the one specified for safety reasons. You can instead remove some of the load or try to redistribute it.

What happens if tongue weight is too light?

In case you don’t load your trailer as indicated, an effect known as trailer sway can appear. This means that the trailer starts leaning uncontrollably from one side to the other. If the speed is high, this can lead to whipping, which is a more dangerous type of swaying. To avoid this situation, make sure you load your trailer optimally and distribute the load evenly between the front and back sides.

In case you are on the road and notice that your trailer starts swaying, reduce speed and maintain it at a value below at least 10 miles per hour below the speed at which you noticed the phenomena. Don’t decelerate and make sure to keep the steering wheel in a straight-ahead position. When you get the chance to stop, make sure you load your trailer optimally.

Can I exceed my towing capacity?
Even if the dolly may carry your heavier trailer, it is not indicated to exceed the vehicle weight the mover was rated to transport, as this can lead to the frame bending or the motor being overworked. Moreover, a mover that gets damaged by an exceeding-weight trailer can no longer be controlled, so you may end up hurting yourself or the people around you.

Can a trailer dolly move a boat?
Yes. As long as the boat matches the weight capacity the dolly accepts, you will find no problems steering it to the parking space in your garage with a mover.

How do you make a trailer dolly electric?
Some manual models can be motorized by installing a special kit that allows using a drill to make the wheels spin. Keep in mind, nevertheless, that if you use this system, you need to move your trailer only on a flat surface, as driving it on a slope can become dangerous.
