If you know how much easier it is to hook and unhook from a fifth wheel than to lower and raise from a gooseneck then you will absolutely love changing your trailer with this adapter. After a year it has made life with my race trailer so much faster loading and unloading every weekend.
This technically works but the craftsmanship is terrible. I had to fix a couple welds on the gussets, finish cleaning up the pin holes they didn't fully cut out and clean it up for finishing. The weld spatter was significant. I wouldn't recommend this if you're looking for a presentable piece on a nice trailer but it's probably good for farm use. I expected a better item for the price but it's not useless.
Was wanting to change my three trailers from gooseneck hitches to 5th wheel king pin hitches. Researched and found etrailer who kindly put up an informative video about there product, application & installation. I ordered the conversion hitch, received it quickly just as I ordered it. Installed it, and am very pleased with this conversion hitch. I also had some other trailer issues and found everything I needed on there friendly web-sight.
First impression is that i am very happy with the product. There was a small amount of weld splatter on the part, but was able to remove it with a wire wheel, used some greaser to clean the area and finally wiped it down with alcohol. It is primed and painted and will be ready to roll in the morning.
Works great. saves me from removing my fifth wheel hitch to pull my gooseneck trailer since i use my fifth wheel for work it is always in the bed of my truck. Others i have looked at are smaller if you are planning on carring it in your toolbox for multiple trailers but for my application it works great i prefer the bigger pad since my trailer has a lot of tounge wheight thanks again etrailer
Paid a few bucks extra to get it here in two days. Actual price for shipping was less then the quote while buying, that was awesome. Minor detail was the fact that my trailer pin holes were not in perfect alignment with the world, but it really does not matter once its hooked up. And on top of that, anyone buying this hitch, is not hooking to a 40,000 lb trailer and needing the truck to raise the trailer. Hitch is fine just not 100% straight to the world. This is an amazing part. Yes its bare metal and yes there are a few sharp edges that could be cleaned up. BUT, if you are looking for a show piece then buy the one that cost $300.00 bucks. If you want quality and functionality then this kingpin adapter is amazing. I will swap this adapter every time I hook to a crappy goose-neck bone shaker.
Great product. Very well constructed and easily exchanges with my goose neck ball reciever.
Robert E - 03/23/2018This is the second I have bought from etrailer as I bought another gooseneck trailer and needed another adapter. These work great and are so simple to switch out.
Works great. Allows us to use the 5th wheel hitch for both the horse trailer and 5th wheel. Easier fir myself to hook up as well.
I, just got it swapped out about 1:00PM. this afternoon. Pulled my trailer about 4mi. Everything went good, and it is simpler to hook to P/U. I, like it! Mike
Product had some sharp edges that I easily ground clean. I have not used this adapter yet as my trailer towing plan had changed. However I will keep for future towing of gooseneck trailers. I think it is well built and will handle the task it is intended. This adapter is a good tool to have in your arsenal when the towing of gooseneck trailer with a fifth wheel hitch.
I always order these for my trailers and have always got a good working functional products with free shipping can't beat the price or quality a+++
Great price and customer service. Product was delivered on time and I was notified by the etrailer staff the moment it arrived at my house. Very well built and sturdy product. The only negative I would say is the plate is very rough. I spent a half-hour grinding on it to make it smooth enough to take it to powder coat. A little more finish work on the final product would be nice so the consumer doesn't have to put labor into it before they can paint or powder coat it.
This makes hooking up my trailer so much easier than the goose neck. Easy to install since i already have a 5th wheel hitch in my truck. All it took was a little paint to match my trailer and ready to roll. On took like 4 days to get my order. Will be getting more products from them in the future.
Although the first shipment of the gooseneck to fifth wheel hitch was not what I had ordered. After a quick phone call to Etrailer they emailed the return information and I received the correct part thre days later.
This adapter is a very strong well constructed unit that comes unpainted so you can paint it to match your trailer. Etrailer was recommended to me by a friend and I am happy to find this company. They are competitive, have a well rounded product offering, and an easy to use website.
For the price you would think the product would have been painted or powder coated other than that I enjoyed the product the hitches work great. Thank you for building a very Superior product!
Order came quickly. Web page easy to use. Bought adaptor to convert goose neck to fifth wheel. Adapter in order to plug in trailer lights/brake plug into my truck. Adapter cheaper than making one from scratch.
I am very happy with this purchase
Good parts and service I will continue to buy from etrailer
It fit perfectly worked great and was amazing easy to install. This will make my life so much easier. Thank you!
Great product. Received it fast
Good 2 day delivery. Good customer service Brenden was right there straightened out the 2nd order (my mistake) and confirmed both were shipped. The product looks good will know more after installation thanks
Just exactly what was advertised. The product was what I needed and the customer service was above reproach. I will be a return customer.
Product was very well built...order was held up from shipment due to holiday...I assume...took two call backs to get it to shipp. but all in all a good company and great product.
