Video Transcript for Review of etrailer Gooseneck and Fifth Wheel Adapters - Fifth Wheel Adapter for Gooseneck - KPG5-Q30

Michael: Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this Gooseneck to Fifth Wheel Trailer Coupler Adapter. This is going to allow you to convert your gooseneck trailer to a fifth wheel kingpin adapter so that you can pull it with your fifth wheel hitch.This is a inner tube and outer tube assembly so it's probably not going to be necessary for everybody. We do sell the inner tubes separately. If you already have a outer tube assembly that's going to fit, you probably don't need this whole assembly.

This is mostly for people whose outer tube has already been damaged. They're wanting to switch it out. Or if the inner tube that we have on our site are not going to fit for you, this is a weld-on application so you will need to weld it in place. It's going to be very permanent for you. It's not something that you can switch out, off and on, depending on which hitch you're connecting to.

A big step, but this is going to be a really nice option for you if you are wanting to convert your gooseneck trailer to a fifth wheel permanently.This is a square tube. You can see our inner tube dimensions here. We're at right about. Turn this for you. Right at four inches for our inner tube and our outer tube, right about four and a half inches.

Our outer tube length is the standard 20 inches and we are going to have the industry standard kingpin on the bottom there, so it should work with all fifth wheel trailer hitches. This is a really nice sturdy steel construction so it's going to hold up well. It's got a weight capacity of 30,000 pounds and it is a raw finish so it should be very easy to get welded in place for you. You don't have to worry about grinding off paint or anything like that.And it is adjustable, the height here. You can see we've got a pin.

This will allow us to adjust the height. We've got four different height holes here, so we can adjust up to eight inches. And each hole is right about two and three-quarters of an inch separated from center to center, so that'll give you nice little increments that you can adjust to make sure that your trailer height is going to line up with your hitch height. Very easy to change, just pull out that pin, slide it in place. And then you got the clip here that goes on the other side to make sure that that pin doesn't wiggle free.We also have two set bolts here that will tighten down once we have the height where we need it so that will always be there. You won't get that rattling around. It'll be nice and tight for you. This does meet the SAE J2738 standards. You can trust it's going to hold up well, do a good job for you. You can see we've got the reinforced gussets here to make sure that we're going to have a nice, strong connection to our hitch so that we can pull that trailer along with us.The pin and the pin holes are seven-eighths of an inch, so should be very easy to get everything set up the way you need it if you are wanting to convert that gooseneck trailer to be pulled with a fifth wheel hitch.We do have other options here at etrailer.com. If you need a round tube or something like that, we do have lots of options available for you so I'd encourage you to check those out if this is not going to meet your needs.That's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

It's beefy, which is what I wanted. Though I have to complain about the packaging. It arrived in an enormous box, 5 times the size of the Hitch. While there little chance of damaging this chunk of iron in shipping, one would want to believe the box would be commensurate with the actual size of the product. Too much waste in packaging/shipping, driving the price up.

Works good fit the trailer I bought to replace the 2-5/16 hitch that was on it. I only use king pins on my farm.

Very rugged construction, gave me several options to adapt to my trailer. I had to modify it to fit my particular application but I have been using this trailer for a year and have had zero problems with the assembly. Approximately 30K miles on a trailer loaded to 26K lbs full time.

I rarely give an excellent review as I always feel there is room for improvement, but this service was excellent. I ordered this coupler on Monday and it arrived via UPS on Thursday. It is the correct part and appears to be excellent quality. I won't hesitate to use this company again and to recommend it to others.

Review from a similar e GN to 5W Adapter in Gooseneck and Fifth Wheel Adapters


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!

A great way to make your trailer more secure to your tow vehicle. No josseling around from a loose ball connection. Easy hook up, less jacking. Lower your Jack’s to the ground and snug it up. Unlatch and pull out.

  • Towing a Gooseneck Trailer with a 5th Wheel Hitch
    Ram Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-Q30 is both the inner and outer tubes. The inner tube is 4 inches while the outer tube is 4-1/2 inches. All of the square inner tubes only that we have are 4 inches. But there is another way to tow the gooseneck trailer if all you have is a 5th wheel hitch. Assuming you have industry standard above the bed rails to mount your 5th wheel hitch you can use a gooseneck hitch plate that fits those rails such as # 49080. I have linked...
