Prevost XLII
The XLII, also written Le Mirage XLII or XL-II, followed the XL, and Wikipedia calls it the second generation of the XL line. Prevost says production started in January 2000 and that the XLII models got a facelift in 2004. Used-coach listings on the independent site Prevost-Stuff show XLII motorhomes from converters such as Marathon and Royale, sold as non-slide or double-slide coaches.

About this model
Prevost's motorhome history page says production of the Le Mirage XLII started in January 2000 and that the XLII models were given a facelift in 2004. Wikipedia says the XLII came in 40-foot and 45-foot versions, dropped the fluted stainless-steel lower body cladding of the earlier XL and used flush-mounted side windows.
The X3-45 followed. Prevost dates the X3-45 launch to 2006, and Wikipedia describes it as a revision of the XLII with a longer wheelbase. No source opened for this profile names the first or last model year of an XLII conversion shell.
