And Aerohead, I know relative to what would be achieved from lengthening and enclosing it wouldn't be as significant but could worthwhile gains be seen from adding length but not enclosing it on the end? Access to the boot is important for my work and enclosing the tail makes that more difficult.
Thanks for the input folks!

Short of a proper boat tail,the open,'box-cavity' is the only other technology Hucho said offered us any gains.
Here's a semi-trailer setup
Here's a VW transporter with a cavity.
A true boat tail might offer a 30% drag reduction,whereas a box cavity appears to peter out at less than a 8% improvement.
