heeyyyyy CONGRATS on the Admin position, Les - of anyone, you are probably the most qualified to fill those shoes.
The best thing I added to my Harley was the specially fitted plastic spare gas can. Well, well worth it if you aren't familiar with the route you are taking. Running out of gas these days is not a good idea. (just too many crazies out there). I had a 1-Person tent that took up less space than a gallon jug.
Those in the 4-wheel rigs should consider some way to carry extra fuel and potable water if you are going to venture into parts of the country you are not familiar with.
(I guess I would stress: shelter, food/water and fuel for everyone).
