Joining the selection is the Goplus Classic, which can be left outside extensively without showing signs of rust, thanks to its protective black powder finish. It also features hardened steel gears, for years of reliable use. Like some others, this electric model conveniently offers a manual crank handle, so you won’t need a separate one on hand for backup.
For a top-notch automatic model that comes with a simple rocker switch, look to the Lippert Components Electric, which can be counted on to lift or lower a travel trailer RV with ease, with just the flip of a switch. It operates quietly and efficiently, thanks to its noise-reducing helical cut gears. It comes with four handy LED lights for use in the dark.
Those who prefer a sturdy manual choice can hardly go wrong with the Reese Towpower, which provides reposition capacity and includes a durable, weld-on mounting bracket. Its top-wind design ensures easier cranking, and its thread and trust bearings help bring down the force of friction. It features an easy-to-fold, cylindrical handle that locks securely into the storage position.
Determining Your Lifting Capacity Needs
Set a small length of pipe across the scale, and one across the brick.
The first thing to consider when buying a jack is its lifting capacity. Choose one that is too small, and it won't be able to lift the trailer safely, if at all. If you choose one that is too powerful, then you are just throwing away money needlessly. When looking at the lifting capacity rating on various models, it is important to note that this is for the tongue weight, and not the weight of the entire trailer.
If you can find a gross trailer weight rating somewhere on your trailer, then determining the lifting capacity you need is easy. The tongue weight is somewhere between 10 and 15 percent of the trailer weight when fully loaded. Even if you don't load your trailer to its maximum capacity, it is still best to err on the side of caution. We recommend choosing a jack capable of lifting slightly more than 15 percent of the gross trailer weight. If you have an older trailer though, the GTWR may no longer be legible. In this case you will have to calculate the trailer weight yourself.
If you are sure your tongue weight is 300 pounds or less, you can use a home scale to determine its exact weight. Place the scale on a sturdy stand that is roughly equal to the height of the coupler when it is attached to the towing vehicle. With the trailer fully loaded, place the coupler on the scale. The displayed weight is your trailer's tongue weight.
If you think your trailer's tongue weight is over 300 pounds, you can still use a home scale, you'll just need to rig up a couple of things. Take a brick roughly the same thickness as the scale and place it three feet away from the scale perpendicularly from the trailer. Set a small length of pipe across the scale, and one across the brick. Next take a flat beam and rest it across both pipes. Tare the scale to adjust for the weight of the beam and pipe. Make sure to put wheel chocks behind the trailer's tires to ensure it doesn't move anywhere. If your trailer still has the old jack attached to it, you can rest the jack's footplate or wheel on the beam one foot from the brick and two feet from the scale, with the coupler raised to the normal towing height. If you don't have a jack currently on your trailer, you will need to raise both the brick and scale up to your coupler's normal towing height before proceeding. Then place the coupler directly on the beam one foot from the brick and two feet from the scale. This should be done with the trailer fully loaded. Taking the displayed weight on the scale and multiplying it by three will give you the tongue weight of your trailer.
Different Needs For Different Uses
When choosing your tongue jack it is important to take into account what kind of trailer you have. A tongue jack on a boat trailer will be subjected to different stresses than one attached to an RV. If you have a boat trailer that is solely for freshwater use or are looking for a jack for RV use, then a simple powder-coated model will suffice. On the other hand, if you launch your boat in saltwater and are buying a steel jack, then it is important to buy a galvanized model, so it can stand up to this corrosive environment. Another option is to purchase an aluminum model, as this type of metal naturally stands up to saltwater corrosion, though it may oxidize and discolor over time.

When looking at tongue jacks, you will probably notice that some have a foot plate, whereas others have a wheel on the bottom. Each of these styles is better-suited to certain uses. Most recreational boat owners will want to choose a wheeled model. These allow users to move the trailer around more easily by hand, such as making small adjustments to its position when attaching it to the hitch. If you have a boat that is so heavy you will never push it around by hand, then there is no benefit to a wheeled model and you may as well choose one with a footplate for the extra stability it offers when uncoupled from a vehicle. The same goes for those looking to purchase a tongue jack for RVs.
Wheeled models generally come in three different styles: small single wheel, large single wheel, and double wheels. Small wheels have a tendency to dig in on soft surfaces like gravel and dirt, so we recommend a large single wheel when possible, unless you have a very small boat. Double wheels are a better option for larger boats, as they make it significantly easier for one person to move a trailer on any type of surface.
What Else To Consider When Choosing A Tongue Jack
Now that you know your lifting capacity needs, and what kind of trailer you should buy based on your use, it's time to look at some other factors that can play into your decision making process. Tongue jacks come in both bolt-on and weld-on models. For most users, a simple bolt-on model is probably best. They are generally more affordable, more readily available online and in stores, and don't require a professional to handle the installation. It is important to note however, that you need measure the width and height of your tongue before purchasing a bolt-on model to ensure it will fit properly.
It is also a smart idea to look at a tongue jack's travel distance. They generally have somewhere between eight and 15 inches of up and down travel. Ideally the more travel the better, as it will be more versatile to work with a range of vehicles. At the bare minimum you need a jack that can lift your trailer's tongue a few inches above the height of your hitch. Another thing to look at is the retracted height, especially if you often travel over rough terrain. The smaller the retracted height, the less chance of the jack hitting the ground as you drive over bumps.
