I don't think the Lexor is on a Sprinter chassis. You should consider asking this question in a more suitable RV forum. There is a yahoo group for pleasureways for example. More objective opinions are perhaps in a forum that does not specialize in one brand.
I own an '05 Plateau on an '04 Sprinter chassis; owned a '99 Excel on a Dodge chassis before. I am pleased with the quality of Pleasureways and how long they stay at that high quality... Al
