Due to the high hitch design, fifth wheel trailers generate chucking forces (fore/aft) that are transmitted to the truck. All solid joint hitches, of which the Andersen is one, will effectively transmit those forces to the frame of your truck. All trailers differ as other factors such as length, axle design and weight distribution come into play. This is why you will read many anecdotal threads regarding fifth wheels not chucking with various hitches..
There are many pin box aids such as MorRyde that would help with your chucking problem. I had a similar problem except my wife lasted only a half an hour because the chucking was so severe. I fixed my problem with a Trailer Saver TS3 air hitch.
If you have a short bed Ram, I wouldn't reverse the pin adapter on your Andersen hitch. You will tow fine for many miles but there will be a time when you are backing tight on uneven terrain and could take out your rear window.
Here are some suggestions: Sell the Andersen while it is still new and get yourself an air hitch. You have nice new gear; why not protect both your truck and trailer with a soft joint hitch? The Reese Goosebox will help with chucking due to its low hook up point and reduced hitch angle. Tow with the trailer level and load your trailer at the ends instead of over the axles, more pin weight is better.. This will reduce the tendency of the trailer to rotate and create chucking forces.
If your setup has the ability to use the TS3 and you are willing to drop the money, you will be thanking me everytime you tow. As your trailer goes over a bump, the pin pushes down and forward at the same time. Due to the high hinge design, the TS3 compresses and retracts at the same time, dissipating both bouncing and chucking forces.
Good luck and welcome to the forum.
