Look at the DRV as a heavier built - higher class unit, but don't disappoint yourself thinking that it's assembled by guys in white lab coats like a Mercedes commercial.
Quality is an industry wide issue - and you will have some problems. Look for a good warranty, a service department you like, and know that your DRV has better walls, frame, construction and higher end features than the class of 5ers below it.
Think of an Escalade, but open the hood and you see GM just like a Tahoe.
