I can't get enough cupholders. Fortunately, up front the Sprinter is blessed with numerous cupholders. There are two on the dash, one with the pull out ashtray, another if you remove the ashtray and the side panel at the doors bulges for placing water bottles in handy reach. Still, we found these portable door cupholders that fit at the windows.
With the cab seats turned around and at the back end with the sofa we had a dearth of cupholders. We had been using the above cupholders in the back with the sofa but always had to remove them when converting the sofa to a bed. So, I installed this one in the back to hold a drink while sitting on the sofa...
When not in use it folds up like this...
I also installed one up front on the side of the armoire which is reachable by either driver or passenger seat turned around. You can get them at a lot of RV and marine supply stores.
The creature comforts are important in a B. Do any B converters consider this kind of stuff? Previous to my Legend, GWVan was providing one of those flip down center console sofa armrests with cupholders. It went away just before ours was built.
Any other good examples or suggestions?
