I had to round the edges on the male end to fit into ANY 2" receiver.....even another Reese receiver adapter. Other than that, it's just an extension and does what it's supposed to do. 647789

Must be a manufacturing defect because the pin does not fit through the holes that have been pre-drilled, so the product is worthless. If it was usable however it does appear to be what I was looking for of extending my hitch out away from my vehicle. 417871

  • Solutions for Clearing Slide-In Truck Camper with Ball Mount for Towing Boat Trailer
    The longest standard hitch extender we have available for a 2 inch receiver is an 18 inch long adapter like the Reese # RP11004 which you have already tried. Please also note that using this and most other extenders will reduce the overall capacity of your trailer hitch. This particular unit will reduce it by 35 percent (most others reduce it by 50 percent). You will just need make sure that the weight of your loaded trailer does not exceed the reduced capacity on your hitch. I'm not...

  • 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 Reese 18" Extender # RP11004 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) and reduce the overall weight capacity by about 35%.

  • Maximum Length Of Hitch Extension for Use with Blue Ox Tow Bars
    Blue Ox hitch-mount tow bars such as their Alpha # BX7380 and Avail # BX7420 can be used with a hitch extension up to 12-inches in length, part # BX88264, but Blue Ox cautions against longer hitch extensions. The potential risk is damage to the hitch receiver tube, not so much to the adapter or to the tow bar. Use of almost any extension or adapter will apply more leverage to the hitch tube, much in the same way that sliding a length of pipe over the end of a tire iron will give you...

  • Hitch Extender Solution for Setup with Weight Distribution
    The install of the weight distribution system you mentioned will add a bit more clearance between the trailer hitch and trailer so you'd gain a bit of clearance there. The best setup for a hitch extension type solution would be the replacement shank part # EQ90-02-4500 which is pretty long. A hitch extension like the part # RP11004 that you referenced can't be used with WD systems so the longer shank is the way to go if needed.

  • Comparing Reese and Curt 18 Inch Hitch Extenders
    One of the biggest differences between Reese adapter # RP11004 and the Curt model # C45796 is the warranty. Curt ball mounts and extenders are generally covered for 1 year. The Reese model though has a limited lifetime warranty. On both the shank that fits into the 2 inch receiver is solid. There isn't a difference in the steel wall thickness; you're looking at approximately 1/8 of an inch. Regarding the tongue weight capacity reductions: The Reese extender reduction has changed...

  • Availability of Hitch Extension Longer than 16 inches Rated for Weight Distribution
    We have the Reese 18 inch extension part # RP11004 which has a 6,500 lb weight rating when used with a weight distribution system like you mentioned using that would be your best option. This extension cuts the capacity of your hitch by 35% though so you'll need to keep that in mind as well.

  • Hitch Extended to Keep Trailer From Hitting Flat Bed Truck While Turning
    Since flat beds are longer than regular truck beds situations like yours can occur more often than with a regular truck. Using a longer ball mount or a hitch extender is a viable option. Since the longest ball mount with an 8 inch drop is # C45338. It measures 9-3/8 inches from the center of the hitch pin hole to the center of the ball hole. If that is not enough length then an extender will need to be used. The use of an extender reduces the tongue weight capacity of the trailer hitch...

  • Can Reese Extension # RP11004 Be Used with Motorcycle Carrier
    I wouldn't recommend the use of a hitch extender with a motorcycle carrier under normal circumstances as that adds quite a bit of leverage and torque on the hitch it's installed in. This # RP11004 cuts the hitch capacity of the vehicle it's installed in by 35% so you'd have to verify your hitch has the needed capacity.

  • Can 18 inch Extender be Used to Pull Boat Trailer Behind Travel Trailer
    The Reese Hitch Extender for 2 inch Trailer Hitches # RP11004 can be used to tow a boat trailer behind your truck-pulled camper. There are a few things that you will want to keep in mind though. Even though you can pull a boat trailer behind a bumper trailer it is illegal is many states. The max Tongue Weight (TW) is 400 lbs and max Gross Trailer Weight is 4,000 lbs.Keep in mind that even though this might have a fairly good TW capacity, your TW capacity is reduced by 35 percent.

  • How Much Does The Reese Hitch Extender Reduce Tongue Weight
    Almost all hitch extenders will cut your tongue weight in half. However, Reese has confirmed their Reese Hitch Extender part # RP11004 will cut the tongue weight of the trailer hitch by only 35%. If your hitch is rated for 500 lbs tongue weight then the new tongue weight will be 325 lbs compared to 250 lbs with the other options. I recommend to use an extra long ball mount if you can get away with it because they do not reduce the tongue weight capacity of your hitch. The Hidden Hitch...

  • Recommended 18 Inch Hitch Extender to Clear Truck Camper on Ford F-350
    The longest standard hitch extender we have available for 2 inch receivers is the Reese # RP11004. This particular extender measures right at 18 inches from the center of the hitch pin hole on your trailer hitch to the center of the hitch pin hole on the adapter's receiver. You can take a quick measurement out from the center of the hitch pin hole on your existing trailer hitch to see if this length will clear your camper's overhang. If you find you need a bit more length, you can also...

  • Can I Use a 18 Inch Hitch Extender with a 2016 Ford F-150 and a Swagman XTC2 Bike Rack
    A hitch extender, like the Reese Hitch Extender for 2" Trailer Hitches # RP11004, can allow you to move the hitch point 18 inches from the your OEM trailer hitch on your 2016 Ford F-150. However, the draw back of using a hitch extender is it will cut your hitches over all capacity by 50 percent. You will have to calculate the weight of both the Swagman XTC-2 2-Bike Platform Rack, # S64670, and the weight of your bikes to find your total tongue weight. As an example, if your rack weighs...

    For your Ford F-250 with truck bed camper, the Reese Hitch Extender for 2" Trailer Hitches - 18" Long # RP11004 will get you out from your camper with a towing rating of 4,000 lbs which will not be enough for your Jeep. If you happen to have a 2-1/2 inch hitch, then you can use the Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 which will give you a 6,000 lb towing capacity at 24 inches which may be enough depending on your particular Jeep.

    The Reese Hitch Extender # RP11004 that you referenced really just moves the location of your receiver back 18". You install your Weight Distribution (WD) system the same exact way, it will just sit further back from your vehicle. This extender is rated for 4,000 lbs Gross Trailer Weight (GTW) and 400 lbs Tongue Weight (TW). When used with a WD system those capacities are increased to 6,500 lbs GTW and 650 lbs TW.

  • How To Determine if Reese Hitch Extender RP11004 Would have Enough Weight Capacity for Towing
    The hitch extender part # RP11004 is 18 inches long and has a 4,000 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 35 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...

  • Can Reese 18 inch Hitch Extension RP11004 Flat Tow a Vehicle Heavier than 4,000 lb
    You are going to be fine using the part # RP11004 because you are flat towing a vehicle which doesn't have the same type of stress on a hitch like trailer does since there isn't tongue weight. This has a higher capacity when used with a weight distribution system which a WD system lowers the effective tongue weight on the hitch by distributing some of it to the front axle. It has no effect on total trailer weight. So since reducing tongue weight allows the # RP11004 a higher total trailer...

  • 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 # RP11004 that you referenced. Using a hitch extender cuts the tongue weight capacity of the hitch it is used on in half.

  • Can 18 Inch Reese Hitch Extender be Used With Reducer for 2-1/2 Inch Hitch and Weight Distribution
    It would be safe for you to use the 18" Reese Hitch Extender for 2" Trailer Hitches # RP11004. This extender is able to be used with a reducer and it is also compatible with weight distribution. It will reduce the capacities of a hitch by 35 percent but has a maximum capacity with weight distribution of 6,500 lbs towing and 650 lbs tongue weight, whichever is lower. For your application with a heavy-duty hitch that would be the 6,500 lbs/650 lbs capacity, which is more than enough...

  • Does Longer Ball Mount Reduce Hitch Capacity by Same Amount as Hitch Extender
    Hitch extenders like the part # RP11004 reduce the tongue weight capacity of the hitch they are installed in. This one in particular does so by 35 percent which is less than most of the other options. Longer ball mounts like the part # 80232 do not cause the capacity reduction. This is because there isn't the added movement of having an additional hitch connection.

  • Recommended Hitch Extender for Lark V-Nose Travel Trailer for More Turning Clearance

You will want to note the use of this extension will reduce your hitch's weight capacity by 35% according to the manufacturer. This will give you a max tongue weight of 520 lbs when using weight distribution.

  • Can Truck Bed Camper Extend Past Rear Edge of Short Bed Pickup
    It's really going to depend on the camper and whether it was specifically designed for a long bed truck. Some are designed to work in either a short or a long bed, but if it's been designed as a long bed only the camper's center of gravity will likely end up behind the rear truck axle. This is inadvisable because this significantly reduces the amount of weight being applied to the front truck axle which will have negative effect on steering and braking response which would be a very dangerous...

    This is a common problem but in your situation an extension such as # RP11004 will work perfectly. The use of an extension reduces the tongue weight capacity of the trailer hitch by 50 percent. Since the tongue weight of your trailer is only 150 pounds the reduced hitch capacity won't be a problem. If you want to save some money you could also use Curt extender # C45796. This extension is rated for 3,500 pounds gross trailer weight and 350 pounds tongue weight. The tongue weight capacity...

For a weight distribution system then that would be properly rated you'd want the part # RP66541 and you'd be set.

Even when considering that the adapter reduces the tongue weight capacity of your hitch by 35 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...

We have two trailer hitch receivers for this truck, but if you don't already have a trailer hitch, I recommend the Draw-Tite # 75607 which is rated much higher so your capacity will be limited by the truck and not reduced by the hitch.

You should note that using this will cut the capacity of the hitch by 50 percent. If you towing capacity is over double the weight of your trailer you'd be good.

The extension is designed so that it can either be used in its 34 inch configuration or be cut down to 24 inches in length, which is perfect for your needs. When cut down to 24 inches, the extender has a 6000 lb towing capacity or if used with a weight distribution system, the capacity increases to 8000 lbs which would work well.
