When installing a trailer coupler like the Etrailer A-Frame Trailer Coupler, part # CA5100B, you want the coupler right up against the edge of the trailer frame.
This coupler is a weld-on coupler for A-frame trailers. I would recommend having a qualified welder or trailer professional install the coupler.
I have linked an FAQ on trailer couplers and all of the A-Frame trailer couplers we have available. view full answer...
I do have weld-on, a-frame trailer couplers in which replacement parts are available but the A-Frame Trailer Coupler w/ Round Jack Hole part # CA-5280-RB is not one of them. The Demco 50-Degree A-Frame Trailer Coupler part # 12660-97SP and Bulldog Heavy-Duty Cast Head Coupler part # BD44150W0317 both have replacement coupler repair kits, the Demco Composite eZ-Latch Repair Kit part # DM6008 and the Repair Kit Fulton Wedge-Latch Cast Head Coupler part # F670801.

The A-frame couplers we carry, like # 12660-97SP, are weld-on applications and cannot be bolted on to a trailer frame. Any welding should be done by a qualified welder in a shop that works on trailers. The coupler you have reference accepts a 2-5/16 inch diameter ball. I have included a link to all of the A-frame coupler options for you to view. view full answer...
Based on my research the Shelby 5107 coupler looks to be an A-frame coupler that accepts a 2" ball, though I was unable to find the weight capacity as this seems to be an older coupler. For a replacement coupler there are a couple different options, depending on the weight capacity you require. These are bolt-on A-frame couplers that accept a 2" ball:
- 5,000 lbs: A-Frame Coupler with Black Paint Finish # CA5100B
- 7,000 lbs: Sleeve-Lock A-Frame Trailer Coupler - Flip Latch # CA-5196-B view full answer...
Yes, the Sleeve-Lock A-Frame Trailer Coupler # CA-5196-B that you referenced is a weld-on coupler designed to fit 50 degree A-frame trailers like you mentioned. Nearly all A-frame trailers are 50 degree so it's hard to find A-frame couplers that are designed for a different angle. view full answer...
This A-Frame Trailer Coupler w/ Round Jack Hole # CA-5280-RB is manufactured in China.
We do have similar options like the Buyers Products A-Frame Trailer Coupler w Jack Hole # 3370091595 and Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole # 12660-97SP that are both made in the USA if that is what you are looking for. view full answer...
The best replacement for your Shelby A-Frame Coupler 5104 is the A-Frame Trailer Coupler part # CA-5400-B. The Shelby 5104 fits a standard 50-degree a-frame, has a 13,000 lb weight capacity, and uses a 2-5/16" hitch ball. The A-Frame Trailer Coupler also fits a standard 50-degree a-frame and uses a 2-5/16" hitch ball but has a 14,000 lb weight capacity. In order to install this trailer coupler you will need to cut the old one off and weld the new one on.

Most A-Frame Trailer Couplers have a standard of 50 degrees. I produced a short video for you showing the angle of the etrailer A-Frame Coupler, part # CA5400.
I have also linked an FAQ on trailer couplers. view full answer...
It would appear that that your 1978 Airstream had the standard 50 degree a-frame style coupler. You can verify this to ensure that the etrailer A-Frame Trailer Coupler # CA-5280-RB will fit correctly on your Airstream.
I personally prefer the auto latching style couplers like the Demco 50-Degree A-Frame Trailer Coupler # 12660-97SP. This coupler for me is cleaner and works simpler with the latching system. The connection for the jack has nuts welded on to the bottom of the plate making... view full answer...
The great thing about a-frame couplers is that they basically all can fit and interchange with each other. You could easily remove the Ram 5000 jack you have on your trailer to replace it with the Demco A-Frame Trailer Coupler # DM14793-81 that you referenced. view full answer...
I found a few pictures of the coupler on your 2019 Winnebago Minnie 170k Travel Trailer and you currently have an A-frame coupler.
The most likely replacement option is the Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole # DM13205-95 which is for trailer frames that have the standard 50 degree frame and requires a 2-5/16" hitch ball. The 50 degree A-Frame is the standard but it wouldn't hurt to confirm that the 50-Degree A-Frame is in fact what your trailer uses.

For your Pro Series A-Frame Coupler for 2 inch ball, I recommend the Pro Series A-Frame Trailer Coupler with Trigger Latch - 2" Ball - 5,000 lbs # PSE338050303 as a replacement. There is not a latch repair kit for this coupler, so you will need to replace the entire coupler. I've attached a video to assist you. view full answer...
The Demco 50-Degree A-Frame Trailer Coupler part # DM16680-52 will fit any trailer with a standard 50 degree a-frame which is almost all a-frame trailers on the market today. Therefore, yes, the Demco 50-Degree A-Frame Trailer Coupler will fit an ATC trailer. You'll simply need to mount the coupler, use the holes as a template to drill your own, and then you can continue bolting on as normal. view full answer...
Thanks for the photos, and I can confirm that you do have an A-frame style of coupler. We do not have a latch repair kit by that manufacturer for an A-frame coupler for a 2 inch hitch ball, so the best we can offer is a new A-frame coupler. There are both bolt-on and weld-on options available.
- Bolt-On: Demco A-Frame Trailer Coupler with Jack Hole - eZ-Latch # DM14793-81
- Weld-On: A-Frame Trailer Coupler - Yoke Latch # CA-5210-B

I did some checking and the a-frame coupler with the most distance at the widest point is the Bulldog Collar-Lok coupler part # BD028384. This coupler has a 11 inches at the widest point. Is there a reason you need one that wide? All that really matters is the angle of the coupler as it matches your frame. Nearly all A-frame trailer have a 50 degree angle where the coupler installs. The # BD028463 would install on a 50 degree angled A-frame trailer. view full answer...
So long as your Airstream trailer has an A-frame, then yes, you can use the A-Frame Trailer Coupler - Underslung # CA-5335-B.
There is no way for us to know what couplers fit any specific trailer, but so long as you have an A-frame then there won't be an issue with this one. view full answer...
The coupler you referenced does not have replacement parts or a latch repair kit so if the thumb latch is busted you will need to replace the unit with the A-Frame Coupler # CA5400.
You can replace it with the same unit, the A-Frame Coupler # CA5400 which has has an oily finish but the same one is available without the oily finish and a black coat of paint, the A-Frame Trailer Coupler # CA-5400-B.
There is another option if you want to go with a different manufacturer, the Fulton A-Frame... view full answer...
