by:

Quick delivery and a nice hitch



by:

It was perfect just what I needed.



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:

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:

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



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:

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:

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:

Ordered 2 of these. They work great. Thank you.



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:

Great product Welded it on easily



by:

Hitch arrived and already installed! Worked perfectly!



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:

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:

Arrived on time, packaged well no damage also very easy to install. Definitely recommend and I will be posting a YouTube video and review on it soon.



by:

The workmanship on this is impressive. It was perfect for our RV, now we can haul our bikes with confidence.

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:

Very well built hitch. All hardware and very easy assembly. I recieved the item two days after order.



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.



by:

Made of quality material and relatively easy to install. Works perfectly on our 5th wheel. Very satisfied. We plan to haul our e-bikes with it and should handle them with ease.



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:

Very heavy-duty steel and hardware, but paint chips if you look at it. I got this hitch mainly for the multiple mounting options, as I've had trouble figuring out how to get a hitch on my particular trailer. I wasn't able to mount it how I originally intended, but I was able to make it work, and I feel pretty confident that my bikes will stay put.



by:

Joshua B was an excellent person who took care of my order and followed through with emails to make sure I received my hitch! The hitch was heavy duty and better than I expected!



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....

Worked perfectly.
Fit up underneath the
underbelly and in between my frame being adjustable made it much easier. my forest river travel trailer. I highly. recommend this hitch.

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!

  • 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...

  • 2 Inch Receiver Hitch for a Forest River Wildwood FSX 178BHSKX Travel Trailer
    Hi Dave, I'd be happy to help. The VIN unfortunately doesn't provide the frame dimensions needed to identify a hitch, but I was able to look up your Forest River Wildwood FSX 178BHSKX and found the rear frame width to be approximately 71 inches. Based on that frame width, I recommend the Stromberg Carlson Adjustable Accessory Hitch Receiver # SC45MR. It fits frame widths from 49-1/2 inches to 76-1/2 inches, which puts your trailer well within its adjustment range. I like this option because...

    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,...

  • Dimensions Of Stromberg Carlson Adjustable Accessory Hitch Receiver SC45MR
    Hey Dusty, thanks for reaching out. I went out to our warehouse and grabbed one of the Stromberg Carlson Adjustable Accessory Hitch Receivers # SC45MR to grab the measurements you asked for. The end of the hitch tube will extend out past the angle brackets by approximately 2". As far as fitting a U-bolt between the safety chain loops and hitch pin hole, I don't think that's happening. The safety chain flange extends just past the edge of the pin hole, so there would be no way to fit...

  • 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....

    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...

    The only thing you'll need to verify is that the width of the frame on your 2020 Jayco Jay Flight is between 49-1/2" and 76-1/2" (reason being we have no way of knowing the exact width of any trailer frame). 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.

  • Recommeded Front Trailer Hitch for a Pontoon Boat
    Your best bet is to use a universal hitch like the Stromberg Carlson Adjustable Accessory Hitch Receiver # SC45MR. This hitch will fit frames that measure 49 1/2" to 76 1/2" wide, has a 2" receiver opening, and has a 200 lb capacity, or if it's welded a 350 lb capacity. Just so you know, this hitch is not intended to be used for towing and should only be used for accessories. If you have a different sized frame let me know what that is and I'd be happy to find a hitch that fits.
