Hi, my husband and I are comparing the differences between the Reflection 337 RLS and the Solitude 305RE, and we know that the Solitude has the 6 point leveling system and Reflection 4 and we know that there are subtle differences inside like no "Pantry" written on the door and the sink in the bathroom is different etc, but what is the biggest difference to create a $15,000-20,000 difference between the two of them? Is the suspension that much different, or the frames? We are looking to go full-time and I know the Solitude is listed for extended living, but is it possible to do that with the Reflection as well, or is that not advised. Please let us know the major differences as we want to make a very educated decision here and it is definitely down to the 2 of these. Thanks!
