This the L3 version of the V-Class, the longest version. The space inside is long enough for almost every kind of bike.
The carrier is mounted in the existing seat rails with a special kit, this without drilling and is easy to mount and dismount with the appropriate knobs.
Because the original seat rails are not close enough from the back door, PMM-plates are necessary.
Carrier for trekking bikes
Carrier for 3 trekking bikes
The bikes are very close to each other, so there is plenty of space left.
Look at the position of height of the fork mounts.
Adjusting height is necessary, otherwise the steers were struggling.
Also the mudguards are high enough from the floor.
