Rick,
I vote for the pie. That way you can add more functionality later.
I also vote for GPS rather than speedometer connection. It should be more
accurate and easier to integrate to the MH.
Here is an instructables link
http://www.instructables.com/id/Raspberry-Pi-GPS-Tracker/
and here is a $20 GPS GPS USB dongle
https://jet.com/product/detail/e1edbb89de4e4ce3add7f632c1995f25?jcmp=pla:ggl:NJ_dur_Gen_Electronics_a3:Electronics_GPS_Navigation_GPS_System_Accessori es_a3:na:PLA_785706713_43735003609_aud-303405841869:pla-307670825895:na:na:na:2&code=PLA15&pid=kenshoo_int&c=785706713&is_retargeting= true&clickid=43cd3370-05e7-4ce6-8dfb-d3abbda5f03e
used in that project.

There are many other GPS solutions
With the pi you should be able to run data through a spreadsheet to do a
bunch of math, pick out the pertinent data and store it in a different
sheet then zero the original sheet and do it again. Lessor boards are not
compatible with this kind of approach.
