Richie, a novice to Class B RVing recently asked me in a message if I thought there was enough storage room in a Sprinter class B.
My Answer:
First we had stuff in the aisle, which got moved back and forth every night to the driver and passenger seats. That got old real quick. So, we took stock of stuff we didn't use and left it with relatives: extra pans and dishes - we use paper plates and bowls - cuts down on washing - which makes fresh water last longer and you get going faster in the AM.
We reduced out of season clothes, made them layers for cooler weather, and cut down on others that we didn't need past a week - we wash every week on the road. I still keep mine in a Treager pack and move every night from back to driver's seat.
We buy food on a semi weekly basis if it doesn't have to go in the fridge. Our Fridge/freezer holds a weeks worth. An exception to this is paper plates, paper towels and Mountain Money (TP). The last two items we built a storage area for by putting in cup hooks and hanging a hammock type device made out of a net in the top void area behind the back bin that is available upon opening the back doors to the rig.
The stuff in the bathroom that doesn't fit in the medicine cabinet always gets put into the sink before we cruise. I also put an extra shelf on top in the way of using 'museum glue' - a clear reusable gel that acts like glue but will come off objects easily when pulled at a 90% angle - and attaching a narrow plastic basket. I also hung a basket where the shower head was installed, after moving it to overhead.
We have also used velcro tape to hang things or batten down the curtains (those snaps they installed at the factory don't work worth squat!).
Binder clips for holdig 30 plus pages of paper together work great to hold stuff to other areas. suction cup thingies can be used to hod wet wash cloths. We purchased two of those huge (36X72) microfiber towels which while they don't work QUITE like a towel are very effect for a Bath towels ( you have to pat, not rub).
I only carry two pair of shoes, the little lady, well that's a different story.
In the overhead bins we have spring loaded bars placed at the front of those bins that have objects which have a tendency to shift around. Don't let shift happen to you. (I say that was a, that was a joke, son.... a gag.
)
To answer your question directly, Richie, I find we have enough room without having to suffer too much on what we want with us.
