The OBJ file format is a standard way to exchange 3D objects between modeling, rendering, and animation applications such as Maya. With this plugin, SketchUp users can export models directly to the OBJ format as polygonal geometry with materials and texture mapping information intact. Note: the OBJ plug-in is not needed for SketchUp 5.x as this exporter is included in the SketchUp 5 install.Updated documentation for the 4.x version is available.

The mentioned conversion tool avoids troubles with different OBJ implementations, and produces M15 file you will always be able to load. No nuances, no variations :)
