As you can see, most have told of the quality differences. In respect for your request on weights, most Doubletree dealers will have a document showing the floorplans and other specifications, including weights.
While I have not found a similar online document for 2009, the link below will take you to a site where there is an Adobe file (pdf) with information on 2008 models.
I also posted this on the SOITC forum in case you check there too.
