You rang, sir?
It really depends how much time you want to spend on this project, but my first inclination for a "quick and easy" clean-up would be to grab the following:
Meguiar's NXT Wash Soap
Meguiar's Deep Crystal Step 1 Cleaner
Meguiar's Deep Crystal Step 2 Polish
Meguiar's NXT Tech Wax (sub for Mother's FX or Reflections if you like) (if you have a Harley dealer in easy reach, go grab a jar of S100 paste carnauba instead, or even to put over top of the NXT/FX/Reflections sealant you apply)
Also either pick up NXT Speed Detailer or #34 Final Inspection as a QD spray you can use right before or at the event.
for Wheels/Tires, grab Eagle One "All Wheel Cleaner" (or A2Z in the orange bottle if they still have any), and dress the tires with either Meguiar's Hot Shine or NXT Insane Shine (depending on your gloss preference).
For outside trim and inside dash/controls, grab Meguiar's Natural Shine protectant/dressing. This can be cut 50/50 with water to reduce the gloss if desired. You might also want to grab a bottle of Meguiar's Interior Quik Detailer if they have it, since that works great for dusting the carbon fiber or woodgrain on the console, clear plastics, and even the dash/doors.
If you need any spot cleaning for the carpets, Turtle Wax Power OUT! should do the trick; and for windows Eagle One 20/20 will be fine.
While you're at walmart, pick up some of their Microfibers (if you don't already have any good MF toweling) or better yet head to Sam's Club and grab a pack of the blue "Hometex" MFs. Be sure to have several foam applicators on hand too.
I think that about covers it for a quick down and dirty detail. If you want to add a claybar, I'd grab either the Mother's California Gold kit, or some Clay Magic (the blue bar). Use your wash soap as a lube, not the QD spray.
Oh and I almost forgot, if you have leather get the Lexol pH cleaner and Conditioner, they're the best OTC stuff you can get.
Process I'd use is this:
1) Vacuum interior, spot clean carpets
2) Clean all interior non-upholstery surfaces (including glass) and condition/dress
3) Clean wheels and tires /w A2Z (scrub with a brush to get dirt out, then rinse)
3.5) Wash exterior /w NXT soap, dry
4) Wipe down and QD door jambs
5) Meg's Step 1
6) Meg's Step 2
7) NXT (or FX/Reflections)
8) S100 (if you get some)
9) Clean exterior windows
10) Dress exterior trim and tires
11) NXT Speed Detailer or #34
12) Head off in a shiny-azz truck
And there you have it, ladies and gentlemen, the twelve steps to recovery.... oh wait, this isn't an AA meeting.....
Now, ideally, all of that would be done with a quality machine polisher, but if you don't have one you won't be able to get all the accessories in time to do the job. However, it can all be done by hand with satisfactory results. Just be prepared for sore arms the next day
Doing a truck this size even by machine can be a chore if you aren't used to it (more than my fair share of suburbans have cured me of that) let alone by hand.
