There's a Pre Delivery Inspection checklist that's outstanding. I followed it. Took me about 4 hours to go through everything. I second Mountainsam's suggestion to have the oil changed. And pay special attention to the coach (house) batteries. Dealers don't maintain them very well. Mine looked good - but I should have put some load on them because they were garbage. Am now trying to get some compensation but am not sure.
