Take negative feedback posted on internet with a big grain of salt. People are more likely to post negatives than positives, whether it is complaints about restaurants or RVs. If you search for problems with Ford or Chevy-based RVs you'll find lots of issues just as if you look for problems with Sprinters. However, these posts are useful to evaluate features. Typically, Sprinters are the top of the line for most manufacturers and contain their newest features. Some people like these features but some people prefer simplicity. The RT Etrek is great example of this - complicated components but great bookdocking capability. The engine mounted generator has a lot of fans, but there are still proponents of bolting a propane generator to your van. Sprinter mileage is a consideration for many, especially those of us who believe we will see a significant (doubling or tripling) of fuel prices over the next decade. Density of authorized service centers is also a consideration.
