Before Installation, verify the vehicle rear sill will support the required loads.
Remove all objects that are mounted in the overhang / mounting space required by the tail lift (ICC, spare tire carrier, pallet racks, tool
boxes, walk ramps etc…).
The installation can be a STANDARD MOUNT [see Figure 7.1] whereby the bed extension is added behind the rear sill of the vehicle
body. Or it can be a FLUSH MOUNT [Contact DHOLLANDIA for guidance], whereby the bed extension is integrated into the vehicle
floor.
For standard mounts, remove dock bumpers, steps, or any protrusions that would prevent the deck extension from being mounted
flush against the rear door sill.
Follow the chassis cut-out dimensions [Figure 7.2]. Trim the chassis beams, long sills, rear sill to the indicated dimensions.
It is possible to mount the lift at a higher mounting height MPG (e.g. to increase the ground clearance); or at a lower mounting
height (e.g. to fit within a shorter mounting space). Ask DHOLLANDIA to confirm the required chassis cut-out dimensions,
as these might change in relation to the new fitting height MPG.
