I have a solution for you, but the Dexter # K71-725-02 will not work for your 2018 Winnebago because it is only compatible with side mounted #12 Torflex axles.

To answer your questions before letting you know what kit will work, one kit isn't going to be better than the other, they're simply designed for use with different styles of axles. You also wouldn't want to use higher rated components than the frame and/or axles are rated for since you run the risk of putting unintended stress on those components. I'll use the example of using grade 8 bolts when an application calls for grade 5; it may seem harmless, but the metal that the bolts go into may not be strong enough for the bolts and you run the risk of the bolts tearing into the metal and causing other problems. Also, suspension parts rated for a 5500-7000 lb axle aren't going to create as comfortable of a ride as those designed for a 3500-lb axle.

Now, the good stuff. I spoke with one of my contacts at Lippert and they do not make a tandem axle kit, but he said that you can use 2 sets of the Axle Riser Kit for Single Diamond Axles # LC270682 to accomplish your goal of lifting your Winnebago 2106 FBS. This kit has bolt openings 9" apart, center on center, to match the bolts on the frame of your Winnebago.
