Whole Hog is not a fantasy.... Do an Ebay search for a portable LCD projector with an HDMI interface. (Spend about $40.00 or so).... We are staring out a perfect screen.... Don't know if it is daylight readable though.

Why not go "whole hog" and make it a heads up display with projection
capability. Then you could read the info off the windshield, where your
eyes should be focused anyway. Just sayin'.

I'm leaning that way as well. I have a 4 line by 20 character Vacuum
Fluorescent Display that I want to use, which is definitely not PI
compatible. If I could re-position the display, a 5" or 7" touchscreen
could be used. I want to have the display part look like it could have been
installed at Pontiac originally.

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

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.
