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...


Comments
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....

Packaging was very poor, 32" extension hitch just thrown in a box. No projective packaging around it. Paint chipped off reciver end. Box taped up in areas that were damaged. Extension plug completely out of clam shell packaging, not damaged luckily. Seriously, you need to do a much better job of wrapping and protecting parts.
Very disappointed.


Comments
I am very sorry that the hitch extender arrived with paint damage. I will have our customer service team reach out to you. I recommend using a rust resistant paint like Rustoleum to touch up the affected areas to help protect against corrosion.

Gave it 4 stars because I have never owned one before so I have nothing to compare it to. It works good, really seems to ground the truck. I have a Ford F250 superduty crew cab with a 8 1/2 ft Lance light camper that sticks almost 2' past the bumper and I pull a 18' open trailer with a race car on it.




by:

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.




by:

This product works great however I would not go over the weight limit. I try to stay well below it remember it's not a super truss.

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!


Comments
The hitch extender is still doing a fantastic job! Very happy I purchased this product.
Ken Y - 09/20/2018


by:

Great service, price and prompt delivery. Hopefully will help immensely with getting my boat off of the trailer during winter drawdowns like the picture.




by:

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.




by:

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.


Comments
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.
Scott - 08/10/2018


by:

Great extension just had to cut off about an inch to fit it on my truck. I did not receive the pin for it.




by:

Every order from etrailer has been perfect. Everything fits, everything works. Always fast delivery.




by:

Looks good..just pricey
Little more communication
on order received, in stock,and a timely out the door date would be nice.




by:

Great quality product!




by:

It works as advertised.

Worked great

Hitch extension needed for 3/4 ton truck with truck camper mounted with tailgate down. Great product. 25 inch extension after cutting off end. Easy to add safety chains to anchor to truck. Now can bring extra gear in covered 5x8 trailer.




by:

Extender was as advertised, I inserted it into my hitch, measured twice, then cut it off on the line indicated for 24 inch length. Used a metal cutting blade in my 71/2 circular saw and didn't take much time or effort. Noticed that the holes for the pin didn't quite line up, the pin wouldn't slide thru, on both the 24 inch hole or the 34 inch hole. I took a drill and 1/2 inch bit and slightly reamed out the holes. Once done, the pin slipped right thru. My TC is a Lance 1010, 10 foot long. The end of the extender is several inches back under the bumper step of the camper, and when the stinger is put in place, the hitch ball is three to four inches away from the bumper. It looks just right.




by:

This hitch extension is perfect for using with our truck camper to pull the jeep and ATV. We even had an icy jack knife earlier this year in Colorado and the hitch held up splendidly!




by:

Does what it's supposed to. I got it to tow my 3000lb boat when I have my pickup camper on. With this I don't have to crawl under the camper to hook up the boat. I did a 1600 mile round trip a few weeks ago with no problems.


Comments
Works just as its supposed to.

Quality, made in the U.S.A!




by:

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!


Comments
Great!
pkg - 06/08/2020


by:

Really well made, robust, and finished nicely. If you have a camper that extends well beyond your rear bumper, this is the best solution I've found for towing. So far I've used it for only one trip, but it was multiple thousands of miles. It was out of sight, out of mind, which is the way it should be.




by:

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.


Comments
This product continues to be a valuable item. It is very durable.
