We have the 24FBS which is the exact same floor plan. They changed the design of a few things and discontinued the FBS version for 2016. The 2 39 gallon water tanks is part of the "Elite" package. You will love this trailer. It is the perfect "couples" trailer. One thing they have added to the RBS model is an outdoor sink and stove under the water heater. There is a storage compartment in that location on ours. Good luck! Any other questions just ask.
