Reese did a very good job designing the 48" hitch extension. It is more substantial than I expected and it's load capacities are probably understated with good reserve margin for safety. Etrailer's service was exellent in all respects inclusive of product description, ease of ordering, exellent pricing, even better shipping and responsiveness, and perhaps best of all outstanding follow-up. I will be a repeat customer and highly recomend this company as a goto company for all your trailer needs. They obviously care about providing first class service and products. 33612

Ordered my Reese hitch extension from etrailer.com and had it in 2 days. The Reese extension is very well built and beefy enough to do the job. I received excellent shipping and great communication from etrailer during the whole process. I will continue to use etrailer in the future. Love the free shipping....... Thanks 8337

Very Heavy Duty. This suits my application. I wanted to be able tow my boat or trailer with my Slide in Camper. I had to do some modification to get it to fit my Ford factory installed class V hitch (needed to grind off the powder coating). Other than that, it works well. 147829

Well designed and HEAVY. Plate for electrical connector is a little too close to the hitch pin (which makes it difficult to get a 7-pin plug in). Otherwise, no complaints. Works as intended to tow my boat behind my truck camper. 254880

Do you have a question about this Hitch Accessory?


  • Use of Hitch Extension to Tow a Trailer on 2011 Ford F-350 Dually Crew Cab With a Slide-In Camper
  • I have two hitch box extensions for the 2-1/2 inch hitch on your 2011 Ford F-350 Dually Crew Cab, but they both will reduce the hitch receiver size down to 2 inches. These extensions are specifically designed for your slide-in camper with the extended overhang. The first extension is the Titan Hitch Box Extension and Reducer, part # RP45292. This extension will only extend your hitch out 24 to 34 inches, so this will not work for your application that will need 36 inches. The second...

  • Difference Between Weight Carrying and Weight Distribution Ratings on a Titan Hitch Extender
  • The Titan Hitch Box Extension for 2-1/2 inch Trailer Hitches, item # RP45018, has two different ratings because if towed with a weight distribution system (see link) you will be able to tow higher capacities. If the extension is used as a weight carrying hitch, no weight distribution system, then the capacity is not as high. The weight distribution system distributes the weight from the hitch to the vehicle and trailers axles to allow for improved towing performance. I attached an FAQ...

  • How is the Reese Titan Hitch Box Extension Supported and Does it Require Stabilization Chains
  • The trailer hitch on the truck is what supports the extension. The extension is designed to fit in a 2-1/2 inch receiver (measuring on the inside) and the receiver part of the extension has a 2 inch receiver opening. The only thing you need for the extension is a properly sized hitch pin like # 74149. For lateral, back and forth movement of the extension, it is normal to see some play. Reese does not make any lateral stabilization chains for the Titan extensions. You will need to...

  • Trailer Hitch Extension to Tow a Boat Trailer with a GMC Sierra 2500 with a Lance Camper
  • I take it that your Lance camper overhangs the truck bed so you need an extension of some kind. There are a couple of possible solutions. Many extensions will reduce the tongue weight capacity of a trailer hitch by 50 percent. However if you were to use a long ball mount, the capacity is not nearly as affected. A ball mount like # 80232 measures 16 inches from the center of the hitch pin hole to the center of the ball hole. I have linked a video review for you. I have also linked all...

  • Hitch Extender Recommendation for a Ford Super Duty Hauling a Camper and Flat Towing a Honda CR-V
  • The closest hitch extension that we carry for your setup is the Titan Hitch Extender, # RP45018, that you referenced. This hitch extension was designed to work with 2-1/2 inch x 2-1/2 inch trailer hitch receivers only and reduces down to a 2 inch receiver for your Blue Ox tow bar. You will want to measure the height and width of your trailer hitch receiver opening to ensure that you can use this extension with your hitch. When using this hitch to flat tow your Honda CR-V, you will want...

  • Actual Length of Titan Hitch Box Extension for 2-1/2 Inch Receivers Part # RP45018
  • The 48 inch maximum length mentioned in the product description represents the distance from the furthest hitch pin hole on the vehicle side of the extender and the hitch pin hole on the other end. The distance from the hitch pin hole where the extension would attach to the receiver on your truck to the front face of the receiver on the extension is 50 inches. I have edited a photo showing what the 48 inch measurement represents.

  • How Much Rattle and Slop is Too Much for An Accessory Used in a 2-1/2 Inch Trailer Hitch
  • Some accessories fit more loosely than others in any given trailer hitch. If you think that the receiver is getting worn out, I recommend measuring the inner opening width and height to see if it is still at 2-1/2 inches. Also check the accessories you are using. They should be slightly smaller so they can fit in the receiver easily. There will always be some play. The longer the accessory, the more it will appear to move. The Titan extension # RP45018 as an example is so long that a...

  • Trailer Hitch and Extension Recommendation for a 1999 Ford F-350 with Slide-In Camper Towing Trailer
  • Normally, the use of an extension will reduce the tongue weight capacity of a trailer hitch by 50 percent. But, your 1999 Ford F-350 can be equipped with a Titan hitch like # 45297. This is a class V trailer hitch with a 2-1/2 inch receiver. When used with Titan Hitch Box Extension, # RP45292, you will not see a significant drop in tongue weight capacity. This extension only fits the Titan hitches and offers 24 to 34 inches more extension. I did a little research and found that the floor...

  • Why the Weight Carrying Rating is Higher on Longer Titan Hitch Extender # RP45018 than Short One
  • I ran this by my contact at Reese. This is a little tricky but I can explain. If you look at the pictures I have included for each Titan Hitch Box Extension (# RP45018 and # RP45292) you will notice that the distance between the 2 hitch pin holes is different by 3 inches. On the longer extension the distance between the furthest out hole and the end of the receiver is longer which allows it to carry more weight at 41 inches. The 3 inch difference is the key factor.

  • Hitch Extension Recommendation for 2014 RAM 3500 Crew Cab with Bigfoot Truck Camper
  • Assuming that your 2014 RAM 3500 is equipped with a 2-1/2" factory hitch, using the Titan Hitch Box Extension, # RP45018, will work well for you when towing your snowmobile trailer. As for the extension acting like a lever, this is true for most hitch extenders but the Titan Hitch Box Extension, # RP45018, was specifically designed to be used on vehicles with a truck bed camper. This extension is constructed of heavy duty steel and has been tested at higher weight ratings so you should...

  • Tongue Weight Capacity of Titan Hitch Box Extender # RP45018 on a 2002 Ford F-350 Super Duty
  • The tongue weight capacity of the Titan Hitch Box Extension, # RP45018, is going to be 10 percent of the weight carrying rating or weight distribution rating of the extension. In this case, if the extension is used at the 41 inch extension you the limit is 500 lbs WC (750 with WD). If used at the 48 inch extension the limit would be 400 lbs WC (600 with WD). You will need to weigh your trailer tongue weights, fully loaded and ready to tow. If the tongue weights exceed the capacity...

  • Trailer Hitch Extension for 2009 GMC Sierra with 2-1/2 Inch Hitch Towing a Boat with In-bed Camper
  • First, the Ford 2-1/2 inch hitch has be known to have some compatibility issues with some accessories. The problem is that the hitch receiver has more rounded corners than a lot of accessories that have more square corners. In the event you run into this issue, what you can do is gently and carefully remove some of the powder coating around the accessory shank until it fits. Do not remove any metal. This will weaken the accessory. The extension length you need is going to be based...

  • Longer Hitch Extension for Backing Boat Down Ramp
  • If you have a 2 inch hitch we do not have any solutions for this. If you have a 2-1/2 inch hitch we have the # RP45018. 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 # HE18. Using a hitch extender cuts the capacity of the hitch it is used on in half.

  • Hitch Extender to Tow a Trailer with a 2005 GMC Sierra 2500 with Truck Bed Camper
  • First you will need to determine if the trailer hitch on your 2005 GMC Sierra 2500 is a 2 inch or 2-1/2 inch. Just measure the opening width to determine the size. I am assuming that the tailgate is down and/or the camper overhangs the back of the truck thus the need for an extension. I recommend an extension that is long enough to where the face of the receiver is flush with or a few inches recessed under the rear most part of the truck or camper, whichever extends out the furthest.

When measuring a hitch, measure from inside the hitch, straight across to the other side (inside); then inside the hitch, top to bottom. Your hitch is likely a 2 inch hitch if it is a OEM hitch. The Titan Extension, will only work on 2-1/2 inch x 2-1/2 inch receivers. An alternate application is product number HE18, the 18 inch trailer hitch receiver for 2 inch hitches.

  • Is it Recommended to Shorten the Length of the Titan Hitch Extension for 2-1/2 inch Trailer Hitches
  • Cutting the back of the Titan Hitch Box Extension for 2-1/2 inch Trailer Hitches, item # RP45018, off is not a concern as long as you leave at least 6 inches behind the center of the hitch pin hole, and you do not excessively heat the extension when cutting it off. Any other modification like drilling, grinding or cutting should be avoided.

This is true for the 18-inch hitch extension for 2-inch hitches # HE18 from Hidden Hitch. This extender tube fits into a 2-inch hitch and provides 18-inches of extension to its 2-inch receiver opening. All other things being equal the shorter extension is the better extension.

As far as the Titan extension, # RP45018 or # RP45292, I have tested these extensions in a Curt hitch with the 2-1/2 inch receiver and found that it will fit.

If you were make a reducer for the Titan Hitch Box Extension for 2-1/2 inch Trailer Hitches, 41 - 48 inches, item # RP45018, it would lower the weight carrying capacity of the hitch and the extension, and could cause an unsafe towing condition.

  • Why is There a Weight Distribution Towing Capacity on my 2007 GMC Yukon
  • If you are unfamiliar with weight distribution systems check out the links I provided of the FAQ article and video on weight distribution systems. Some vehicles and hitches will have two different towing capacities, one for without a weight distribution system and one for with a weight distribution. Since these systems help vehicles carry the weight of a trailer more evenly on your vehicle axles the rating for with a WD system will be higher than without. Generally speaking you will...

  • Recommendations for Cutting Titan Hitch Extender
  • A horizontal band saw with a blade that can cut steel would be your best option. But even a cutting wheel with a thin disc would work pretty well too. If you have access to a sawz-all that would be an option. But I would go with the first two options if you can before this.

  • Yes, you can use a Titan Hitch Box Extension # RP45018 with the Curt Hitch 15607 that you referenced. The # C15809 is also confirmed to fit your 2008 Dodge Ram 3500 with a factory hitch. You should note the different capacities the # RP45018 has. If you use it at the full 48 inches of length it has a 4,000 lb capacity. Or if you cut it off to use it as a 41 inch extension you would have a capacity of 5,000 lbs.

Even though in your situation, there won't be any tongue weight exerted on the extension, the towing capacity still wouldn't change from 4000 lbs according to Reese. I'm sorry to say at the 48 inch length, the Hitch Box Extension wouldn't be a good choice for your Wrangler Unlimited. It might be possible to use the bar at the 41 inch length,...

  • How Long Can The Titan Hitch Box Extender Part # RP45018 Be On My Truck
  • The hitch box extender # RP45018 you referenced will extend your receiver opening to a maximum length of 48-inches away from your truck. But is also offers the option of being shortened to 41-inches. If you have the hitch box extender at 41-inches the weight carrying capacity is 5,000 pounds, whereas 48-inches the weight carrying capacity is 4,000 pounds. Note that it only works with 2-1/2 inch trailer hitch receivers. I also added a link with FAQ's for you too.

  • Does the Titan Hitch Box Extension Bend Upward at the End
  • The Titan hitch extender # RP45018 does have a slight bend in it closer to the receiver end. This is to help compensate for any sag caused by the length and weight of the extender so there basically won't be a difference in height between the hitch receiver and the receiver on the extender.

  • Can 2007 GMC Yukon Flat Tow a Nissan Altima

On the GMC website they state that the Yukon can flat tow another auto IF it is the 4WD version and has the 2-speed transfer case.

  • Yes, the factory hitch on your 2013 Ford Super Duty truck will need to be removed to install the Curt Trailer hitch part # C15810. If you need trailer wiring you would want the Draw Tite wiring harness part # 18252. For a ball mount and hitch ball you would want the etrailer.com Ball Mount kit part # EBMK25318. You could use the Titan Hitch Box Extension # RP45018 with this hitch as well.

  • Can Weight Distribution be Used with Reese Titan 48 Inch Hitch Box Extension
  • Yes, you can use Reese Titan extension # RP45018 with weight distribution. When used with weight distribution the extension is rated for 6,000 pounds at the 48 inch length. The thing about weight distribution is that when you calculate trailer tongue weight you have to also factor in the weight of anything loaded behind the rear axle of the truck. So in this case it would include the half of the bed camper behind the rear axle. It is tough to determine how much weight is behind the rear...

The weight distribution system you choose will be based on the tongue weight of the trailer when loaded and ready to tow plus the weight of the part of the truck bed camper that is behind the rear axle of the truck.
