The main difference is the material used with these two type of frames, that and of course the design is different. Of course then the person who's welding it together. Notice the material used on this GN trailer.

This isn't the best photo of a 5er RV frame but you can see the difference in the pin box area. This is why most RV 5er manufactures will void the warranty.

The frame material and design are a apple vs orange comparison.
Having said that, I've seen plenty of folks do it but they seem to be mostly smaller 5er's with less weight.
Good luck whatever you do
On edit maybe IB516 can share a photo or two of how some are put together :W
Wow! The first one has at least two 10,000lb axles with duals used for loading heavy equipment that if the ramps sink into the ground would lift a 1 ton dually or larger off the ground in a heartbeat and then as the load moves forward would load the truck to it's axle stops until loaded properly. The change could be in a matter of seconds so a real pounding.
The camper, much lighter, is used entirely different with the max load shift as the husband and wife decide to quit watching tv in the back and head for bed. To use those two pictures to justify knocking a gooseneck adaptor is outrageously ignorant at best.
On edit: The top trailer is rated with two 15,000lb axles and a Med duty tractor. The axles that far back puts much more then 20% of the weight on the hitch also. Kinda dishonest comparing those two trailers don't you think?
On edit again: I down loaded the pdf on the gooseneck trailer shown above... Model 3XGN. Two 15,000lb axles. 30,000lb rating weighing 8630lbs empty. 20ft from the front of the bed to the hanger pivot between the two axles. Long enough to drive 1 12,000lb tractor on to the front of the bed then driving another on the rear of the bed. Enough to go from a negative to a 6000+ lb load on the hitch (not calculating the trailer empty pin weight) in the time it takes to drive the tractor from the back to the front. I know this is RV.net but I don't think even here ignorance is that bad. It had to be a blatant intentional attempt to deceive.


Picture look familiar?
