Fifth wheel to Gooseneck ????

I agree with DSteiner51 on several points.

Yes, from an engineering standpoint there is the possibility to put more stress on the hitch with an adaptor but not an 18-24" "cheater" bar.

Actual increase in leverage is less than 18-24", can't be any longer than max length of the adaptor and may be less.

If I remember correctly in the last 5years plus, there has only been one or max two frames broken with an adaptor but more that have never been converted.

Also agreed, but why add stress to an already questionable situation? That is like playing russian roulette but adding a second bullet to increase your chances of losing.

Pivoting a 5th wheel beyond the couple degrees most new hitches are made to pivot to the sides so that the hitch takes the stress from the truck also far exceeds the extra stress the extra 6 inches or so will ever put on the frame.

While I understand your point, without some real math it is invalid to claim which stress is more or less on the fiver frame. There are several things that mitigate frame stress during extreme side pivot situations, both trailer and truck suspensions do flex and the pin box can tilt on the hitch head. Anyway, the purpose of the hitch limiting side tilt is to prevent contact between the fiver and truck bed rails and avoid other damage to both.

Oh, I agree with you on another point, with the Goose Box, Lippert is trying to capture more $$$. But just because it has the same physical dimensions as other GN configurations doesn't mean it has the same level of added stress as other GN configurations. Much depends on how well the internal cushioning works. And I give them credit for at least trying to engineer the complete system of fiver frame and adaptor and warranting the entire package, something that is impossible from other suppliers.

1. Mine adds 6 inches, not 18" to 24" as some idiot attempted to claim. Moving the hitch down on it's factory adjustment will bring it to nearly that.

2. NEVER, NEVER adjust hitch down from the very top adjustment. Why stress the frame any more then what it is from the factory's very top adjustment?

3. Do the math. The pivot is limited to protect your fancy truck but then it really stresses the frame. Again, do the math.

Facts are facts and the facts are simply that on RV.net more frames have been reported breaking using the 5th wheel hitch then the gooseneck adaptor. Go back and check how many threads there have been. Some where closed by the moderators because of "experts".
