We recommend that you bring soft bags (like a backpack or duffel bag). There is room for two of these in the (lockable) storage compartment. The measurements are:
Dream Sleeper Mini: 1.18m wide x 0.8m long x 0.32m height (not lockable but there is a small compartment in the back, underneath the fridge, that can be locked).
All other Spaceships: 1.04m length x 0.54m width x 0.33m height (lockable)
When you have put your stuff/gear in the storage of your Spaceships campervan, people on the outside cannot see what you have put in the lockable storage area. No worries.
