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.

  • Weight Ratings For Brophy and Buyers Products Hitch Extenders With Steps
    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. Do remember that these both reduce the capacity of the receiver on your vehicle by 1/3rd. So your hitch must have a weight rating of 1,050lbs tongue weight and 10,500lbs trailer weight to reach achieve the maximum rating for the extender. The...

  • How To Tow a Trailer Using a 1999 Ford F-350 With Truck Bed Camper That Overhangs Rear Hitch
    I have good news and I have bad news. The good news is that there is an option that was made for exactly this same situation. The bad news is that it's not exactly cost effective. This entails using the TorkLift SuperTruss Hitch Extension part # TLE1548 which also requires the TorkLift SuperHitch Original Trailer Hitch Receiver part # TLF1002 that is a fit for a 1999 Ford F-350. The longest trailer hitch extender we offer for a single 2" hitch is the Brophy Hitch Extender with Step part...

  • Trailer Hitch Extender For Weight Distribution So Tailgate Can Be Opened
    We do have hitch extenders that will work with a 2-inch trailer htich receiver. There are tongue weight and trailer weight ratings for the extenders you need to pay close attention to. For a 7-inch extension I recommend part # HE06. With weight distribution, this limits th gross trailer weight to 7,000-lbs and tongue weight at 700-lbs. For a 14-inch extender I recommend part # HE12. The gross trailer weight with this extender is 3,500-lbs and 350-lbs tongue weight. We also offer part...

  • Hitch Extender for a 2007 Chevy Silverado 2500HD Short Bed Towing a Horse Trailer
    When you use a hitch extension in a 2 inch or 1-1/4 inch receiver it will reduce the tongue weight capacity of the hitch by 50 percent. But if you have a 2-1/2 inch receiver the tongue weight capacity is not reduced but usually the capacity of he extension is lower than the hitch so you would go by the lower rating. If you have a 2-1/2 inch receiver opening you can use the Titan extender # RP45292 at the 24 inch length. That will give you a capacity of 6,000 pounds; 8,000 when using weight...

  • Recommended Hitch Extension For A 3 Hitch On A 2021 Ford F-250
    The 3" hitches Ford is using are throwing everyone for a bit of a loop. With that being said, I do have a couple options for you to check out. First will be the TorkLift Cannon Hitch Extension - 3" Ford Super Duty Factory Hitch # TLE1636. This will measure 32 inches long, so it is longer than you need, but it is also rated up to 3,600 pounds towing and 360 pounds of tongue weight. This jumps up to 7,200 pounds towing and 720 pounds of tongue weight when a weight distribution system is...

    The HitchMate TruckStep Extendable, Hitch Mounted Step for 2" Hitches - 9" x 6" - 500 lbs # HE4045 is the only extendable step we carry that reaches that far. We do have hitch extenders that have the step for that same purpose like the Brophy Hitch Extender with Step for 2" Trailer Hitch Receivers 18" # ST18 or the Brophy Hitch Extender with Step - 2" Hitches - 19" Long - 6-1/2" x 17" Platform # ST12 (14inch extension). These won't extend quite as far out from the tailgate to give you...

  • Can a 48 Inch Long Combo Bar be Used to Make a Hitch Extender
    Combo bar # 80948 is used in hitch fabrication and is not technically an extender. It has no hitch pin hole to secure to the receiver on the trailer hitch. The longest regular extender that we have for a 2 inch trailer hitch is # ST18 at 18 inches long. If you used it with a long ball mount, # EA40, then you would have a total of 32-5/8 inches of extension. Please note this will severely reduce the tongue weight capacity of the trailer hitch. The use of the extension alone reduces the...

  • 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.

  • Recommended Cargo Carrier with Ramp to Clear Spare Tire on Jeep Wrangler
    The Flint Hill Goods Cargo Carrier # C18112 is a really nice, aluminum carrier that is compatible with 2 inch trailer hitch receivers. When determining if a particular carrier or accessory will clear the spare tire on your Jeep, you will first want to take a quick measurement. Measure the distance from the center of the hitch pin hole on your trailer hitch receiver, to the outermost edge of the spare tire. The Flint Hill Goods Carrier features a distance from the center of the hitch pin...

  • Longer Hitch Extension Recommendation for 2 inch Hitch

  • 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...

  • 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...

  • Recommended Hitch Extension for Towing Boat Trailer With Camper in Bed of 2017 Ram 1500
    We do have a few options you can choose from but it is worth noting that a hitch extender will reduce the overall weight capacity of the trailer hitch on your 2017 Ram 1500. I recommend either using the Brophy 18" Extender with step# ST18 or the Buyers Products 18 " Extender with Step # 3371804017. Both products give you 18" of extra clearance (from center of hitch pin hole to center of hitch pin hole). The Buyers Products extender reducse the overall weight capacity by about 35%. The...

  • Recommended 14 or 18 Inch Hitch Extension for Boat Trailer with Weight Distribution Hitch
    The first thing you will need to do is find the tongue weight of your trailer. This information will be required in order to determine if you can use an extension. I recommend using a scale like the etrailer Trailer Tongue Weight Scale # e99044. I am also attaching a helpful article on how to determine trailer tongue weight. That being said, it is likely your tongue weight will not exceed the capacity of the extension based on what you have told me. Again, you need to measure your tongue...

  • Longest Available 2-Inch Hitch Extensions for Use with Truck Bed Camper
    For a 2-inch hitch the longest hitch extensions we offer are the 60-inch # TLE1560 and 48-inch # TLE1548, both from TorkLift. However, these only work along with a TorkLift brand SuperHitch dual-receiver type hitch that has the strength and included safety chains to handle the extra stress from the trailer load being further from the hitch. To use one of these you will need to also install a SuperHitch. The longest standard 2-inch hitch extension that will work in any hitch is 18-inches,...

  • Recommended Hitch and Hitch Extension Compatible with 2011 Ford F-350 and 7K Trailer
    If you have a 2-1/2 inch opening in your factory hitch receiver on your 2011 Ford F-350, then you can use the Reese Hitch Box Extension and Reducer for Titan 2-1/2" Trailer Hitches # RP45292 along with a weight distribution system for your 8,000 lb capacity. If you have a 2 inch factory trailer hitch receiver opening, then there is another option. If you are right at the 7,000 lb trailer weight or under it, you can use the Brophy Hitch Extender with Step - 2" Hitches - 18" Long - 6-1/2"...

  • Can Brophy Hitch Extender ST18 be Used to Add Distance Between Trailer Hitch and Trailer
    Yes, the Brophy Hitch Extender # ST18 can be used as a way to extend out the distance between a trailer and the hitch it is installed in. With this extender you'd gain an additional 18 inches. Only thing you'll want to keep in mind is that when you use a hitch extender like this you cut the capacity of the hitch it is installed in by 50 percent. I attached a picture of this used as a hitch extender for you to check out as well.

  • Can I Use the Brophy Hitch Extender With Step on my 2017 Chevy Silverado While Towing
    When using the Brophy Hitch Extender with Step - 2" Hitches - 18" Long - 6-1/2" x 17" Platform # ST18 it will reduce your hitch's capacity by 1/3, so if you've got a 1200-lbs max tongue weight capacity on your hitch it will only be 800-lbs/8000-lbs towing- when using this extender. This isn't an uncommon issue that's encountered, so you'll need to do some math on what you're towing and make sure that you wouldn't be over those numbers when doing so. This will be the case with any hitch...

  • Availability of Hitch Extender for Andersen Weight Distribution Hitch
    We have a few options for an extender that you can use with weight distribution. Depending on the length you need there is the Brophy Hitch Extender For 2" Trailer Hitch Receiver 14" Long # HE12 and Reese Hitch Extender for 2" Trailer Hitches - 18" Long # ST18. The only problem with these is that they will reduce the capacity of your hitch.

  • 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.

  • Extending a 2 Inch Trailer Hitch to Clear Camper in Truck Bed
    The longest extension available for a 2 inch trailer hitch is 18 inches, like # ST18. But if you also used extra long ball mount # EA40 that would get you to 32-5/8 inches from the center of the hitch pin hole to the center of the ball hole. Please note the use of an extension will reduce the tongue weight capacity of the trailer hitch by one third, other extension reduce by a half..

  • Brophy Hitch Extender for Weight Distribution System
    Based off of the information you have provided me I recommend the Brophy Hitch Extender with Step item # ST18. This is an 18" extension that fits a 2" hitch receiver and has a 6.5" x 17" step. It is rated for up to 7,000 lbs if used with a weight distribution system and 3,500 lbs if used without. However, it does reduce your hitches towing capacity by 1/3rd so you would want to check and make sure your hitch has enough capacity to support this extension. We do not offer the HitchGATE spare...

  • Recommended Hitch Extender for 5,000 lb Travel Trailer with 500 lb Tongue Weight
    Some extensions are not safe to use for towing no matter the weight. I do have an option for you, but it does require a weight distribution system for your 5K travel trailer. I recommend the Brophy Hitch Extender with Step # ST18. With the proper weight distribution system, this extension is rated for up to 7,000 lbs and up to 700 lbs tongue weight. You will want to make sure your trailer hitch receiver is able to use weight distribution and the trailer and weight distribution system's...

  • Limits of Brophy Hitch 18 Extension with Step # ST18
    If your Tundra maximum tongue weight (at your Tundra receiver) is 880 pounds and then you attach the Brophy # ST18 extension, then your maximum tongue weight at your Tundra receiver is reduced from 880 to 586 pounds. However, the receiver on the Brophy extension sticking out is only 350 pounds, so you have to go with the lower of the two: 350 pounds. If you attach a cargo carrier that weights 40 pounds by itself, then you have 360 pounds left available for actual cargo to put on the carrier....
