At stealth vans we source base vans, (usually Mercedes sprinters) build them to one of the layouts below and then sell to the open market. If pre-ordering or placing a deposit early enough customer preferences such as colour choices, handle choices wooden trim choices can be accommodated.
The standard layouts we do are as follows, in all versions the front lounge/ kitchen area remains the same. The differences are at the back.
LWB
Bunks+garage (5 birth) (as shown in pics below of example van
Bunks+bathroom (5 birth)
Bathroom+garage (2 birth)
MWB
Bunks (5 birth)
Garage (2 birth)
Bathroom (2 birth)
The bunks system we use are fully adjustable up and down and removable which allows for different size children, or the option to swap a bunk for shelving/ bike storage etc.
