I just wanted to thank you and your family. I’m assuming it’s a family business. I can’t believe how helpful and communicative and prompt…
It was just as pictured and fit very nice. I would recommend it to anyone wanting to upgrade on 5th wheel hitches like we did!
Item was shipped out quickly, just as described, and communication was good.

Today, we’ve got ourselves a fifth wheel hitch for T Built camper converts it from the kingpin to a ball in the bed of your truck. So we have everything laid out here. Since this is a closed kingpin box, we’re gonna drill a hole here and here with a holesaw to gain access to the bolts that are down here and here. So, we’ve marked our first hole. Now we hit it with a centerpunch and we’re gonna drill it with a pilothole and finish it out with a 3/4 inch bit.
Alright, we just finished our first hole. Now we’re gonna install the hitch and guess where to put the next hole to get the bolts. So far, I have drilled one bolt hole. Now, I’m gonna drill an access hole to get the bolts tightened up in here. Let’s get started.
Now that I have that hole drilled, I can attach the hitch to mark the other three holes and we will be good to go.
I’m going to show you two ways to install this hitch. One way by yourself and the other way with a friend. First thing you want to do is just slide it over the kingpin. Get your bolt all snugged up in there. Snug it up just a bit so you can mark out your other three holes and prepare to drill those.
I’m going to hold this up. Normally, we’d tighten it up to allow for the slot, but I’m just going to hold it so Erica here can finish it out.
I’m going to mark the last three holes.
I’ve got one bolt in. It’s snugged up and we are going to drill the next three holes with the hitch in place cause its easier. Now that we have all of our holes drilled, including these side ones here, we’re gonna snug up all of the bolts and then torque them up to 275 pounds with a torque wrench.
We have torqued the bolts to instruction specifications, and now we are going to plug up the holes, give a nice clean finish and this is your T Built product and gooseneck adapter hitch.
Tools needed for this installation is a 1 and 3/4 inch holesaw, a 1 and 1/8 inch ratchet and wrench, 3/4 inch drill bit. Also, if you choose not to bolt on the hitch you can weld it right here and it can be easily removed with a cutting wheel if you ever decide to take it off and sell your trailer.
One reason why you should purchase this product is that it doesn’t directly bolt on to the kingpin itself. It bolts to the kingpin box, dispersing the weight across the whole kingpin. Here we are with our final product. Also, to keep in mind, T Built offers hitches ranging from 12-inch, 15-inch and 17-inch and then one with a offset of seven and a half inches — also in those sizes. They also have one that adjusts from 12-17 inches if you don’t know what size you need.
