Lacamastraveler, I have a 2014 Solera and have added Hellwig, Sumos and Bilstein (wish I had gone with the Koni shocks instead). I do a great deal of off-the-grid travel. All the upgrades have helped the side to side rocking, but they don't prevent it entirely. My approach is to go v-e-r-y slowly. The rocking can be quite unsettling! If it starts rocking, I stop and proceed even more slowly.
