Use a gooseneck adapter in pulling a fifth wheel?

Hello Friends, we are in process of upgrading from 23' Thor Scamper TT to a fifth wheel to go cross-country. We are newbies with just 1 year of trailering experience. Our TV is 2009 GMC 2500HD Duramax, (40k miles) K&N air Intake and EGT Gauge. full fifth wheel accessories. 9200 GVWR. 3.73 rear gear ratio. Looking at ~ 30' unit. Any advantage to gooseneck attachment other than being able to use the truck bed when unhooked? Thanks kindly for advice regarding this question. Carl & Peggy

    A lot of mfrs =expressly= void a warranty if a GN adapter is used. Lippert =will= warrant =some= frames if a Reese Goosebox is used, though. You need to check with the mfr, and get the answer IN WRITING!

    I'm in the same size boat as you, wanting to stay around 30'. My top 2 choices are the Jayco Eagle HT 27.5RLTS and the KZ Durango 1500 D284RLT. Both are "half-ton-towable", but don't let that fool you; they really need a 3/4 ton to comfortably tow them. The Jayco Eagle HT's all gross out at 9,950 lbs and the Durango 1500's gross out at 10,500. While the KZ is my #1 choice overall, the fact that there's exactly 1 KZ dealer in all of AZ means that I'll likely go with the Jayco.

    FWIW, I use the B&W Turnover Ball base with their Companion FW hitch and love them both. B&W makes several different versions of the Companion, so there's one that will fit your needs.

  • Got it. We do a lot of horse trail camping with friends in IA. We noticed all their Lakotas and other brands were strictly built as gooseneck.
  • Too bad you can't see some of the 5ver to gooseneck mod 5vers in rural areas first. In ruaral areas lots have been modified because they also tow horse and stock trailers so they modify their 5vers. Lots of 5vers for sale with rippled and damaged front end because of the mods.
  • Thank you all for the advice. I will definitely look into the Andersen Ultimate Fifth Wheel option.

  • I would call your trailer manufacturer, or the manufacturer of your trailer chassis, and ask their opinion. Or, take a look at the Andersen Ultimate Fifth Wheel Connection.

    Some people say using a gooseneck adapter may void warranties and put more torque on the front of the trailer chassis. Other claim they used and never had an issue.
