Hazmat, if you are considering ramps to get dock high for your new rig, I would caution against it. I rarely encounter a situation where I can't load or unload freight because I am not dock. When this does happen, if at the shipper, I get dry run pay and they send a dock high truck. At the consignee, arrangements are made to unload at another location with a ramp.
Your narrow width may not accommodate a full size dock leveler and I don't think you have any rear deck overhang to catch a dock plate. In my opinion, the chance of damaging your van trying to get dock high and using a built in dock plate, far outweigh any benefit. If you carry your own dock plate, well then maybe, but that's just one more piece of pus to add to the two ramps you will need to carry.
For Mrnewbie, with a cube van, especially if it is a DWR with the wider box it might work. He also has 16' to carry the ramps and/or portable dock plate. He also may have a customer(s) who require him to be dock high pay him accordingly.
Personally, for general van expedite, I don't think it is worth it.
