I'll second that Landau is the more "luxo" version, and the Pursuit more of an entry level coach, although the two models do have many common traits. Also x2 on the air dump.

Depending on your budget and your intention to keep the motorhome, you might consider installing a set of headers. One big improvement for us has been changing out the absorption refrigerator for a residential unit. There are a few models right around 10 cu ft that are slim enough to fit without major surgery. DW really likes the frost free feature.
