We took delivery of our 20MRB on 3/31. As we haven't been in a hurry to get her out yet, we have taken our time to get the essentials into it.
The previous TT had one large outside compartment that I could get three larges storage totes in plus a smaller one. The 20MRB has three outside compartments but none big enough to get any of the totes in. I need to measure for smaller totes, discard what I really do not need or, as the DW suggested, put the stuff in the bed of the TV. I really like keeping trailer necessities with the trailer.
Not sure about inside storage yet. Still stocking it a bit at a time.
