Video Transcript for Stromberg Carlson Adjustable Accessory Hitch Receiver Feature Review

Hello, neighbors. I'm Steven here at etrailer.com. Today we're looking at this Stomberg Carlson Adjustable Accessory Hitch Receiver. Now folks, this is a universal hitch. It's designed to work and use on travel trailers and fifth wheels. It can be either bolted or welded on by a professional onto your trailer.

You can possibly weld it on yourself. Just note that it is only rated at a class two of 350 pounds if it is welded and installed by a professional welder only. Otherwise, it's only rated at a class one 200 pounds. Now the receiver opening is a standard two inch by two inch tube here. You get your safety chain attachments, all the hardware here needed and bracketry if you need 'em to mount to your specific needs.

Everything's a heavy duty steel that's been black powder coated. It's gonna resist rust, corrosion, and it's got a nice kind of reflective, glossy finish to it, which is pretty nice. It does install on various trailer frames. It'll work on either C channel or an I-beam frame. So if you're using C channel, it's gonna work on the horizontal wall.

Now, as I mentioned, you got from 49 1/2 inches all the way out to 76 1/2. So these side pieces here can extend out (metal grinds) all the way if you need 'em. And they got bolt holes here to mount it to your frame. You can either use it like this or if you need to invert it, you can invert it like that. So keep in mind, you got a lot of versatility with this hitch.

(metal clanks) And on the front you can kind of see over here you got a hole, and right here. What you'll do is once you get this set to the length that you need it, mark it, either do a center punch or a paint mark or something and then pull these back out, drill a hole through that, and on the backside of this guy, there's a welded nut and then you can put a bolt all the way through there for extra, you know, hold it from sliding and whatnot. Folks, this is not, I repeat, not designed to be used for towing. So please do not try to tow anything with this. This is just to add a connection point, if you will, to carry like a bike carrier to carry some bikes, maybe a cargo carrier, something like that. Again, the weight rating is a class one, 200 pounds or a class 2, 350 pounds only if it's been installed and welded on by a professional. Now I want to kind of show you some dimensions here real quick. This image will also be available on the product page. You can scroll down and find that in the ask the expert section of the page and you could also pause the video if you need to and write down any kind of dimensions you need. Keep in mind it is adjustable, so you got lots of variations that you could use if need be. Well folks, that's gonna wrap it up for our look at this Stromberg Carlson Adjustable Accessory Hitch. Again, 49 1/2 to 76 1/2 inch frames. I'm Steven. Thanks so much for watching. I hope this information's been helpful. Stay safe out there and have fun on your travels.

I Love the Stromberg Carlson RV and Camper Hitch! As a matter of fact, I bought (2) of them. I mounted them to the frame on my 2020 Shasta Phoenix 25RE 5th wheel and it was Eazy Peazy! I connected the (2) hitches together using an 18" hitch extender that runs thru the stock square bumper. I bolted them to the frame of the 5th wheel, not the provided tabs from the RV manufacturer. The frame is stronger than provided tabs, in my opinion. Works Great and is Solid!

Looks great, John! Where are you taking that dirt bike to?



by:

The pre drilled holes on my travel trailer plates don’t line up with the trailer hitch so I’m trying to find someone that can drill new holes. It requires someone with the a proper drill and drill bits

The hitch is a universal-fit item, it's not RV-specific. Welding the hitch in place is also an option, if you'd care to go that route....



by:

Has worked out great. I mounted it to the frame of my camper so I could put a basket in it and haul my generator.



by:

I have a Newmar Cypress 2006 and it has the connections for a hitch, but of course they no longer make it. I had to have someone make an adapter plate for my hitch to line up the holes and it worked perfectly. THANK YOU so much for sending this unit quickly. Although the packages was damaged all the parts where there and it has fit my needs. Please to try out with bicycle rack next month on a long trip.

It is doing exactly what was intended. I had the unit welded so I didnt have to worry about it coming loose. Thank you.

Glad we had the right fit so you can transport your toys a little easier Paul. What trip are you looking most forward to this camping season in your RV?



by:

Easy bolt on to 5th wheel. Did have it welded because it is now the low point and when my rear drags it takes the pressure off my trailer. It has been a great asset to put our bike rack on

Bolt on bumper is still performing well after a year and multiple trips. I have a reared on my 5th wheel and it has had to drag several times with no damage holding up well



by:

Excellent Accessory Hitch! I mounted it on the rear of my Coachman travel trailer to use for my Carry-All. It is as strong as my receiver hitch on my truck! If you are searching for an adjustable hitch, you can’t go wrong with this one from etrailer.com!



by:

Although I am satisfied with the end result, installation was a bit involved. I elected to mount this hitch on the rear of our camper trailer in order to support a bike rack. The 17mm holes that were needed in both the frame and hitch were challenging to drill. I strongly recommended using titanium bits. Start small and work your way up. Most of my time was spent adjusting and measuring to ensure a proper fit. Once completed, the hitch is a solid base. No worries with reliability.



by:

I really in joy my receiver hitch it can do so much more than what it is rated for I have pushed mine to it limits by towing ( at my on risk of course) but it is rugged and extremely well-built I’m well pleased with my purchase

It is tough it can haul way more than what it is rated for i have put mine to the text more than once I am really pleased with it



by:

I like that it’s universal for different width frames and relatively easy to install if you know what you’re doing. Down side was that two bolts were the wrong thread size. Bolts were M16 and the weld nuts on the frame were 5/8.



by:

One of the welded nuts on the hitch was not welded straight. So the through was hard to start. Had to cut the weld off one side of the nut and reweld it. Other than that I got it mounted on my trailer



by:

What I was looking for. Good price and free shipping.



by:

The hitch looks and feels very solid. The installation was pretty straight forward but drilling the bolt holes for the adjusting part was a bear, getting those to line up took a bit.



by:

I don't have the capability to welding so I planned to drill and mount this. It worked great, but would have been easier if I had the recommended 17mm drill bit. I did use a 43/64" and it worked great. Had to spend part of my day going out on town to get the larger drill bit.



by:

It was perfect just what I needed.



by:

Quick delivery and a nice hitch



by:

Product fit well and performs great.



by:

So far it is a great hitch. The only thing I had an issue with was the welded on nut on the back side. The bolt wouldn't start correctly. I would rather just have a hole and put on my own nut. Other then that, it was easy to install.



by:

Assembly to back of RV trailer was straight forward. Have to try it out yet.



by:

Easy to install! We'll built and shipping was super fast!

Still working strong. Was so easy to install and adjust to fit.



by:

The hitch is way better than expected from reviews I’ve read. Excellent customer service and would buy same product again from e-trailer.



by:

Worked very well installed on my travel trailer for use as a bike rack for two eBikes. Total weight with carrier is 175lb. Therefore I’ll add a few beads of weld to enhance the strength where bolted to frame. Hardware and hitch assembly were heavy duty. Took nearly four hours since it’s heavy (65lb) and bulky to handle. Would recommend.



by:

Great product works as intended!!!!!



by:

Bought this particular one for my rv because I didn't have any room to mount anything other brand due to power stabilizing jacks and the way they mounted the rear bumper. It works as intended

  • Does the Lippert 2" Accessory Receiver Hitch for Up to 66" RV Frames Come w/ Installation Hardware?
    Hey Kelly. The Lippert 2" Accessory Receiver Hitch for Up to 66" RV Frames item # LC78DX does not come with installation hardware. I checked with Lippert and they said that this hitch is intended for use with RVs that are prepped for a hitch, meaning there would already be brackets welded to the frame of the RV. If you would like a more universal hitch that does come with installation hardware, I recommend the Stromberg Carlson Adjustable Accessory Hitch Receiver item # SC45MR. This hitch...

    Hi Leonard! The Stromberg-Carlson Adjustable Hitch # SC45MR will most likely fit, but I don't have the frame width measurement for your 2019 Grand Design 2970RL handy, unfortunately. That said, this will fit frames that measure from 49-1/2" to 76-1/2" wide, which tends to cover just about everything. I would be very surprised if you got a measurement that did not fall between these. Have you measured your frame by chance? If you do end up getting a measurement that this wont work with,...

  • Will Stromberg Carlson Adjustable Accessory Hitch Receiver Fit 2019 Flying Cloud Airstream
    Hey Donald; I'm fairly certain the bolt hole positioning of the # SC45MR will allow you to attach it to that tab. They're 5-7/8" apart on center and sit 1-1/2" down from the top of the bracket. The instructions call for drilling with a 17mm bit so you need to account for the hole size as well. I would compare this to the tab to make sure everything will fit as intended. Also, you need to check with Airstream to see if that is capable of supporting a hitch. Is there any other place to...

  • Can The Lippert 2" Accessory Receiver Hitch # LC78DX Adjust To Fit 61" Wide Frame?
    Hey Mike, thanks for reaching out. I see you already got an adjustable hitch on order but I still wanted to reply to your question. The wording on the part page for the Lippert 2" Accessory Receiver Hitch # LC78DX is really weird. This hitch is not adjustable so I am really not sure why it says "up to" 66" when in reality this hitch is specifically designed for Coachmen Apex units that are prepped from the factory with hitch receiver tabs. So it is designed for a specific 66" wide frame....

Your frame rail spacing is 71", and this hitch is designed to fit widths ranging from 49-1/2" to 76-1/2", so you’re well within that range. It comes with a standard 2-inch receiver, which is perfect if you're planning to use it for things like a bike rack or a cargo carrier. Just keep in mind that it’s rated for accessory use...

  • Do Holes Need To Be Drilled Into The Adjustable Arms Of The Stromberg Carlson Adjustable Hitch
    Yes, if you plan on bolting the Stromberg Carlson Adjustable Accessory Hitch Receiver # SC45MR on then you would need to drill holes in the adjustable arms in order to set them to the correct length. There aren't any predrilled so that this one hitch can fit multiple different lengths. You'll also need to drill holes into the trailer frame in order to bolt it in place as well. To make drilling through the metal easier you'll start with the 17mm drill bit it requires and drill just enough...

    I pulled one of the Curt Adjustable Width Trailer Hitch Receiver for RVs # 13703 from the warehouse and measured it and found that the cross tube was approximately 68-3/8" in length. Knowing how manufacturers are I'm sure the intended size is 68" since the brackets have a 2" lip and both together would add up to 72". I'm sure if we measured multiple the actual length will vary from 68 to 68-1/2". The brackets are intended to sit flush up against the inside of the I-beams and have a bend...

If it is, then yes, you can use the Stromberg Carlson hitch you asked about, which is the following part number: - Stromberg Carlson Adjustable Accessory Hitch Receiver # SC45MR It is very likely your frame is in between those measurements, but you'll just want to make sure it does.
