Congrats, when we were thinking of changing to our MB we looked at the Landmark similar floor plan. Like everything else there were things we liked and some we didn't. One thing we liked was the option of the Mor/ryde IS, but in the end we stayed with RW and did get the IS installed on our MB between Paint and Final checkout, so we were happy we didn't have to spend two days in the Mor/ryde shop again.
