Sounds good. Will be fun to see what shows up!
RollinCole, what are the details of your issue? Not too many ways for these to lose MPG, unless you're either leaking fuel or the engine is way out of tune or the brakes are dragging. If you're putting a lot of fuel out the exhaust as black smoke, that could be part of it, just guessing based on your username...
Let us know if we can help, hope you're able to make it for the cruise.
