The frame of the fiver is still not built for it and there have been many stories here of damage being done. If you do a little research on the interweb, you can see how different the frames are.
The risk woudn't be worth it to me.

Actually I have done my research. I have yet to find a single instance where using the Goosebox has damaged a frame of a fiver under normal towing circumstance, ie: not hitting bad road/holes/etc that cause other damage. In fact, since Lippert does not void the frame warranty while using the Goosebox, it says quite a bit about the product. Please show me where 5er frames are blowing apart while using the Reese Goosebox under normal towing.

My understanding is that the weight is still on the gooseball location over the axle. The pivot point/ball is moved back 4". Therefore, the weight has not moved on the truck, but the pivot point is further back. I am not an engineer but it makes sens to me? The point contacting the truck has not changed.

Visualize the adapter has a 40" offset instead of 4". Pretty plain that the offset affects the truck's geometry even though it is hooked to the truck in the same place. The adapter moves all the pin weight 4" aft of the axle.

I have Ram Short bed. My toy hauler has the radius sides similar to yours. I hit my truck but was lucky enough to just ding the cab and not break the glass. Had fixed mount hitch.

You can get an auto slider for same money you're looking to spend. I got the Demco, but there are others.

You need to retake high school physics. The weight is applied to where the ball is located, as it becomes part of the TV chassis.

I installed the OEM pucks myself. B&W now makes a great manual slider that mates to the pucks. You well not hit the cab going forward in the tow position. When spotting the trailer slide it back.

I'm with Roy on this one. I never took any physics class, just use my logic (or lack of ;-) with that 4" offset the weight I believe is where the gooseneck mount is and not where the ball is. Now in the case of say an Anderson ultimate where its distributed to essentially four corners then yes the weight is 4 inches back but not in the case offset gooseneck. The only thing that would be different is your torquing or twisting the gooseneck mount but not moving the weight back.

Edit: Didn't think this one all the way through. The twisting force that the offset is providing is in effect lifting wieght off the front and placing it rearward. My bad, I'm a little slow lol

Check with your FW dealer. I was told that any and all of the frame warranty was null and void if I used a gooseneck adapter/hitch. Just saying to cover your bases.

Lippert builds the frames, and has stated in writing that they approve the Reese Goosebox pinbox.
I would get the auto slider, even though hitching is a little narrow to align the hitch.

You don't have to get the air bag pin box. If your truck is set up well it should tow well without that.

You can install the MOPAR 5th Wheel Prep package. I installed it in my '14 Ram 2500 and it was pretty straight forward. I also got the in-bed 5th wheel wiring harness.

Next, get the B&W sliding Companion hitch.

$232 -- Ram 5th Wheel Prep
$80 -- In-Bed wiring harness
$1625 - B&W Companion
------------
$1,935

This will be a nice clean setup for little less than your Goosebox option.
