I own a Navion iQG which is the Itaska version of the Winnebago View Profile. I do believe that there is no such thing as a B+. These are C Class without a bed over. I previously owned a B (Gulfstream Vista Cruiser) and spent quite a bit of time on the RV.Net B site. Mr. Roadtrek and others clarified this confusion back then.
If you are looking for a two person C Class I highly recommend the View Profile or Navion iQG which are both made by Winnebago.. Rumor has it the Winnebago will fade out the Navion and other Itaska models and just sell Winnebago labeled RVs.
