I have a Big Tex gooseneck and a 18’ 70PI tandem axle utility trailer. I bought the gooseneck used but bought the 70PI new. I did go through the bearings and they were pretty dry. Their “setup” consisted of the mechanic hitting the lug nuts with an impact and a torque stick.

Definitely shop around for prices and features but remember there are bad reviews with every manufacturer on the internet.
