Most Popular Gooseneck Coupler Adapters for 2018 GMC Sierra 3500

I ordered the Bulldog adapter because I believe their quality is good. The construction of the Bulldog hitch adapter was good. However, the 4” tube was not perfectly round, approximately.030 out of round. This shouldn’t have been an issue, but since my trailer is used and had a Temco hitch originally, the tube wouldn’t slip in. I chucked the Bulldog in the lathe and skimmed .030 of the diameter and it went right in. This review is not written to criticize Etrailer or Bulldog. Just be aware if you’re working with a different brand hitch other than what is listed, there is a possibility of fitment issues.

Great product, fast shipping, excellent communication, definitely recommend these guys!! We painted the square tube/king pin tube red and installed it. Works great, but there is not much of it to see in the pic. Take my word, well built & very heavy duty!!

Perfect for the job if you’re switching from the regular gooseneck hookup to a semi truck fifth wheel set up. Shipping was accurate & I love my adapter! Very easy to attach & real neat finish to paint it whatever color you would like to.
