Best to look at DRVs site for model comparisons. If I remember correctly the Tradition is their entry model and the Mobile Suites is the better choice for fulltime. Each model comes with upgrades over the previous one with the Elite being their top of the line. Typically it has the fiberglass one piece roof and granite counters with upgraded electronics. Each can be ordered with specific added upgrades though.
