I recently bought a truck tent that sets up over the open tailgate. I have a bump/step that became totally useless as it was covered by the tailgate. Then I came across the ST18 extension. Now after the tent is set up, I install the extension then the bump/step itself and your able to step up and into the tent with no problems, and it's also extremely stable!

This is exactly what I needed. Being a long time RV owner, I have purchased many items from E-trailer and have never had a bad experience. Great service, product exactly as described.

    The weight ratings for the 14" Brophy Hitch Extender with Step # ST12 is the same for the 18" Brophy Hitch Extender with Step # ST18. Both are capable of up to 700lbs tongue weight and 7,000lbs trailer weight when using a weight distribution hitch.

  • How To Determine if Brophy Hitch Extender RP11004 Would have Enough Weight Capacity for Towing
    The hitch extender part # ST18 is 18 inches long and has a 3,500 lb trailer weight capacity. As long as your trailer weighs less than that the extender will work just fine. But you also need to determine the weight capacity of your trailer hitch like I mentioned and then determine that 33-1/3 percent of that would be still above the capacity of the extender. That being said the limiting factor is the capacity of your hitch. Using this extension will reduce your hitch's weight capacity...

  • Is There a Hitch Extender that Can be Used with 3,800 lb Trailer
    I like the Brophy Hitch extender with Step # ST18. it reduces your tongue weight by a third instead of most others reduces by a half. As long as the hitch on your 2006 Toyota Tundra has a hitch capacity that can handle the reduction this would work fine since hitch extenders cut the capacity of the hitch they are installed in by 50 percent.

  • Hitch Extender Recommendation for 7000 lb Camper
    An extender like the # ST18 does provide a handy way to provide additional space between the truck and the trailer. The only down side is that using this extender will decrease the towing and tongue weight capacity of your truck's hitch by 33%. This extender itself can handle 7000 lbs towing and 700 lb of tongue weight, but your maximum capacity will be limited by the component with the lowest capacity. Given that your hitch would need a huge towing capacity in order handle the trailer...

  • Can You Use a Brophy ST18 with Weight Distribution
    Though you will want to double check the towing rating of your 1999 Ford F-350 diesel, the weight ratings you listed will work with the Brophy # ST18. That being said, this will allow for a little movement when installed, especially with a weight distribution system. Due to this, you will want to add a couple anti rattle devices, like the Roadmaster Quiet Hitch # RM-061. For what you will be doing, I would go with 2 of these. One for the hitch on the vehicle, and one for weight distribution...

  • Could Brophy Hitch Extender # ST18 Be Used On 2003 Ford F-250
    You didn't mention how long of an extension you need, but the part # ST18 will give you 18 inches of extension which sometimes is enough to allow you to tow a trailer with a camper but that depends on the dimensions of the camper. You should note that using this will cut the capacity of the hitch by one-third. If your towing capacity can handle the reduction, you'd be good.

  • Solution for Adding Mobility Scooter Lift to Ram 3500 Towing 5th Wheel Trailer
    The Brophy Hitch Extender # AT18 that you referenced is capable of handling the weight of the lift you're looking at plus the weight of the scooter itself. Even when considering that the adapter reduces the tongue weight capacity of your hitch by 33-1/3 percent you are in good shape because your Ram is equipped with a Class V hitch that has more than enough capacity. In terms of listed capacities and technical safety you won't have an issue with this setup. With this type of extension...

  • Using Hitch Extender With Weight Distribution
    Using an extender such as the Brophy # ST18 might be possible, but it will depend on the tongue weight capacity of the hitch on your truck. Using the extender will lower the hitch weight capacity by 1/3, so you'll want to find the ID label on the hitch which lists it weight distribution towing and tongue weight capacities. If 2/3 of the hitch towing and tongue weight capacity isn't less than the 360 lb tongue weight of the trailer, then using the extender would be okay. If the trailer's...

  • Longest Hitch Extender with Highest Capacity for Dolly Towing Vehicle Behind Motorhome
    The longest hitch extension for a 2 inch receiver with the highest towing capacity is the # ST18 from Reese. The extender has a 3,500 lb towing capacity. Keep in mind that using an extender like this particular one will lower your hitch towing and tongue weight capacity by one-third. The tongue weight shouldn't be an issue, because car dollies typically don't have a tongue weight much more than 100 lbs. The weight of the car plus the weight of the dolly couldn't exceed the 3500 lb towing...

Even though you can pull a boat trailer behind a bumper trailer it is illegal is many states. The max Tongue Weight (TW) is 350 lbs and max Gross Trailer Weight is 3,500 lbs.

    The MaxxTow MT70070 will reduce your hitch's overall tongue weight capacity by 50%. This adapter is rated for up to 400 lbs tongue weight and up to 4,000 lbs towing.

  • Can Hitch Extender be Used to Help Get Boat Trailer Further into Water to Launch It
    Depending on how the angle of the ramp changes a super long extension may not be a great idea as it would either point the nose of the trailer up super high or down to low. The longest extension we have for a 2 inch hitch is 18 inches and it would be part # ST18 that you referenced. Using this hitch extender cuts the tongue weight capacity of the hitch it is used on by one-third, while most others reduce it by a half.
