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'.

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.

HUD is known technology. Fighter aircraft started the idea, then commercial
and private aviation, now it has trickled down to automobiles. Aftermarket
suppliers now can fix you up with just about any technology your heart
desires. All it takes is GMC bucks. I figure anything that keeps your eyes
on the road and off the dashboard is a good thing. Inattentive drivers
cause lots of problems on the road, and they are not all using hand held
devices. Old farts with too many gages are just as much of a hazard.

As I mentioned above we average 8.9 MPG. I religiously keep tract of our mileage to make sure everything is OK. Two years ago our mileage dropped to 6.5 and engine performance was terrible, so I knew something was up. After LOTS of searching I found a vacuum hose in front of the carb that was split on the bottom side. I replaced it and the performance and MPG was all back to normal. Just passing on info.

Get yourself a good vacuum gage and don't leave it in the package. INSTALL
IT. Then watch it. When it registers below 7 inches of vacuum, lift up on
the gas pedal, and manually downshift into second gear. Then proceed at 10
to 12 inches of vacuum until you crest the hill. Then, up shift to 3rd. It
will improve your fuel economy and make your engine last longer. You will
have a bit more time to enjoy the view out the windshield, too.

Looking back at some older discussions, I noticed that this one did not
generate any replies. I have the same question as Keith V - what is the best
way to drive our GMC in the areas with lots of hills?

Jim, Your corret on the driving habit.
As far as milage, you need to take average of at least 4-5 tank fulls to
get close as the tans never fill the same each time.
I know some will debate me on that, but I know what I have experianced over
milion miles on these.

I try to watch the vacuum gauge. I have one of those dual gauges with vacuum and RPM displays. To be honest, I do not like it as much as I though I would. An upgrade to a dedicated RPM gauge and separate vacuum gauge is on my wish list.
Do you recommend to disconnect the kickdown solenoid switch on the gas pedal?

You have the EBL unit with VSS so your getting the mpg read ing.
That is always a great way to se how things are functionig.
I'm sure you are happy you have the assembly.

Just a very quick look on Amazon finds many HUDs. Unfortunately, they all tie to OBD systems. There were some cheap devices that would reflect your smart phone display on to a piece of reflective film on the windshield, or on to a mirror.
OBD system is an obstacle to many interesting devices for motor vehicles.
