Video Transcript for etrailer Gooseneck and Fifth Wheel Adapters - Adapts Trailer - KPG5-Q25 Review

Speaker 1: Today we're gonna take a look at the square gooseneck to fifth wheel trailer coupler adapter. It has a 25,000 pound weight capacity. Now, this gooseneck to fifth wheel adapter will let you tow your gooseneck trailer with a fifth wheel hitch. It's a unique coupler that'll fit the same as a gooseneck coupler with inner and outer tubes. Those have an eight inch adjustable height to fit your application. It's a sturdy steel construction.

If you notice, it does have the heavy duty load bearing pin and clip is all included to hold it into place. This does meet the SEJ2738 compliance. The range of vertical adjustment, again, is eight inches of height adjustment. The inner tube width is four inches. Outer tube width is four and a half inches.

Total length on this is 20 inches. Pin hole diameter that the bearing pin goes through is a seven eighths of an inch diameter, the weight capacity again is 25,000 pounds. And the last thing I just want to mention is the plate here, the dimensions on this is gonna be nine and seven eighths inches wide by nine and seven eighths inches long.But that should do it for the review on the square gooseneck to fifth wheel trailer coupler adapter with the 25,000 pound weight capacity.

Very good quality. Welds and fit are excellent. I used this to adapt a 5thwheel. The factory pin box was the wrong style to fit my truck and hitch. This coupler adapter allowed me to use vertical adjustment to let my trailer clear the bed of my truck even when turning. As you can see I cut the coupler down to suit my needs and it seems to have worked very well. My only complaint isn’t even really aimed at the part or etrailer but at usps. etrailer shipped the part the next day and I had it within 3days. The box it came in was shredded!!! Again not really the fault of etrailer or the part but y’all might think about using better shipping containers or using a better shipping company. Also wrapping these bigger heavier parts with sharp corners in shipping Cellophane might help keep the boxes in 1 piece. Thanks!!

I can't tell you how happy I am with etrailers. I ordered the wrong part for my flat bed. I was thinking it's going to be a Hassel to return the part and get another. I call etrailers and told them and they emailed me a return form that day. They have fast shipping and great customer service. I'm not one for writing reviews but it's hard to find a company that honors the customer as number one priority. Thanks again etrailers will be ordering alot more from you guys.

I ordered this item and within 2 days it had arrived. Installing it didn’t take over 10 minutes! I use my truck to work during the week and pull my 5th wheel on the weekend! Only thing I’d recommend purchasing is a lube plate to put on the hitch, that way you don’t have to deal with a greasy mess! I’d recommend this hitch to anyone!


Comments
The product is holding up well and works great. It is very convenient being able to switch from my camper to my gooseneck without having the change the hitch out!

I ordered a 30k gooseneck to kingpin conversion for a 40 foot heavy hay trailer. I received my order early. Upon inspection, I was pleased with the construction and then mounted it. it attaches to my single axle road tractor easily. it also provides better stability than the other options available. I am a first time customer and will likely be a repeat customer.

Added a gooseneck 5th wheel to a 14,000# dumpster trailer using boxed 8x8 wfb. Built it to the truck. This product ideal for this project. Welded on with flat plate allowing space for adjustment. Towing made a huge difference with the trailer maxed out most of the time. Turning around is fantastic with the ability to jack it around up to the cab.

My pickup engine went down being unable to pull a my gooseneck with a ball application I ordered your 4 in kinpin adapter for a gooseneck trailer as you can see in the pictures it pinned in perfectly with no trouble at all with your adapter im able to get my trailers moves while repairs are made and with it i'll just have to use the fifth wheel hitch for the pickup witch is much more easy to use than a goose ball

We purchased the adapter to replace a new one from another supplier that had broken during operation costing thousands of dollars. This one was built much better and we are happy with the quality still one year later.

Well built product. Only problem is the holes were too small for my locking pin. Just used a die grinder to open them up a little and fit great. I did paint it also, came bare.
