This dual-function adapter bar lets you extend your hitch beyond your bed-mounted camper and reduce your hitch opening so that you can have a 2" hitch for towing a trailer or mounting an accessory.
Features:
Specs:
This adapter bar can be trimmed down for applications that require only 24" of extended length.
It is recommended that you use stabilizing straps (18050 - sold separately) when carrying hitch-mounted accessories with this adapter bar.

Product has held up great. No issues. High quality
I recently swapped out the stock 2" receiver for a 2-1/2" to allow me to purchase and use this extension to get past the end of my Lance 1010 Camper. I believe I will have no issues now towing any trailer (within allowable spec's) or carrying my motorcycle carrier. Great quality piece. can't wait to try it out...

Excellent! After a year of use still happy I purchased this product...Had to cut it to match the length of my campers overhang but it is perfect now....
Have not mounted it yet but it’s what need to flatbtow a jeep behind my truck with a Lance camper
Excellent product. Easy to use. I recommend finding someone with a metal band saw to cut to length. I cut mine with a sawzaw metal blade and finished it with a high grit sanding disc and it turned out ok- not perfect. I towed my boat behind my truck with the camper on it and it worked good. I’ve also attached my motorcycle rack with my 2013 ktm 450. To be on the safe side calculate your tounge weight before towing.
Have not used the product yet but am confident it will work as expected. Paula was extremely helpful and provided good support and advice. Will definitely shop eTrailer again and would recommend as well!
Received the product on time and as described however two days later I found it on Amazon for $167 vs the $XXX I paid from
etrailer. When I called to see about a price adjustment - they couldn’t assist and offered return and re-purchase from Amazon - minus a $XX return shipping. Lesson learned.
It is working well. Just what was needed to avoid the expense of a trailer.
Great service, price and prompt delivery. Hopefully will help immensely with getting my boat off of the trailer during winter drawdowns like the picture.
Great extension just had to cut off about an inch to fit it on my truck. I did not receive the pin for it.
Love it! I don't have a slide in camper or truck attachments. I simply purchased to increase turn radius and how much I can cut the trailer before jack knifing, works great for tight spots.
Exactly as described and I custom tethered it to the camper bumper for more stability. I did have to drill out the pin hole a little as it did not line up 100% to get the pin inserted, but it is going to work very well.
CURT C45048 HITCH EXTENSION I drive a 2011 GMC 3500HD with an S&S 9.5 slide in camper. I needed an extension to be able to tow my boat behind the truck/camper. I saw this extension was on sale w/free shipping. I ordered on Sunday 9/10 and received it on Wednesday 9/13. The extension looks very heavy duty and it slipped right inside my vehicle receiver. The extension protrudes about 4" past the camper bumper. PERFECT!
All of the welds look like quality welds. I just need to mount my trailer harness and I will be ready to go! Great service, great prices & delivery!

works great. allows me to tow with my cab over camper.
Product is heavy duty, and, tho I haven't used it yet, I expect great results like previous reviewers. Price was good and customer service dealt quickly and favorably on a small issue I had.
I did have to cut 1 1:2 inches off to make it fit in front of my spare, but that was no surprise because I read that other buyers had dealt with the same issue. Chevy/GMC trucks spare tires get in the way a bit. Very satisfied. Have bought from etrailer in the past and don't think they can be beat. Thanks to Caleb for his help.

Really well. I just used it to tow my boat halfway across Washington behind my pickup camper and it worked great. I’ve used it several times now and am very happy with what it allows me to do.
Perfect for a truck camper
This extender works great with our 2019 Ford F350 when using our 9'6" truck camper so we can use our bike rack or tow a trailer. Nice product, great etrailer selection and info once again!

Great!
Absolutely the correct product for my needs. This fit perfectly beneath my Lance truck camper enabling me to haul a 16 foot trailer behind. All the holes matched up to my Dodge RAM 3500 receiver, and because the full length was necessary, no cutting was required. This was, by far, the least expensive bar at this length. Delivery was fast. I have no complaints--only good things to say. Thanks.

This product continues to be a valuable item. It is very durable.
Who do I contact about getting the right extension bar? The one I ordered Is a 2 1/2 inch which I need a 2 inch to slide into my receiver or if you guys have a 10 to 12 inch, 2 inch extension so I can connect it I sent a photo of the end that is 2 1/2 which I need it to be 2 inches to slide into my receiver

I do have an extender that will work for you. It is part # C45796, however is 18 inches long. I will have our Customer Service team reach out to you to send over return instructions.
Great product, worked out perfect for extending passed the cab over camper.
This worked out great for my trip from Minnesota to Montana and back, wouldn’t have been able to do it without it
works as expected, i was worried about trailer sway with the hitch having some wobble, but pulled up to 70 just fine. I like the fact that i dont have to use the factory adaptor on the receiver.
Received hitch extension as promised. The longest hole did not line up with hole in the factory bumper as it was too long and hit on the spare tire. Had to cut about 1" off the align with holes in the bumper and the extension. Product looks good on the vehicle, have yet to try it out with a trailer, but don't anticipate any problems. The wiring harness extension wouldn't fit through the hole in the mounting plate so had to unwire, then pass through the hole, then rewire the plug to be able to mount it to the extension. Looks good now tho.
We bought this extender as an alternative to a 'Super Hitch' that would have cost 4 times as much. Our need was to pull a 17 foot fiberglass boat behind our pickup with a truck bed camper that extended out a couple feet of the box. We pulled that boat about 4,000 miles this summer, and this hitch worked great. Unless you are pulling something with a lot of weight, this hitch is the answer to your problems!
Extension solved our problem of the camper overhang obstructing the trailer hitch. There is some side to side movement with all the assembled components, which can be tightened up by various devices (shim accessories etc.) Manufacturer states that a bit of slop is expected and safe and we have seen no problem with this issue.
the original add said it came with a 2 1/2" to 2" reducer. this did not come with it.

The C45048 is a hitch extender and reducer. One end of the extender should be 2-1/2 inches to fit your 2-1/2 inch hitch receiver opening and the other end of the extender is a 2 x 2 inch opening.
Do you have a question about this Hitch Adapter?

I use this constantly and its perfect. I use it to mount a bike rack while Im using the truck camper. Considering a swing out connection so that I can move it out of the way, but I havent done that yet.
