>>>but I would add a combination jump-pack/inflator (the largest capacity
you can get).
Works great for adjusting tire pressure and jump-starting yourself if
another car isn't available in case you have a dead battery.

Wouldn't hurt to Have a second battery?
With a press of a button, the Sure power 1315 will jump the starting
battery off of the cabin battery.
I run the Propex and an inverter off of the second battery in my Carat
and watch movies with surround sound on the  lap top plugged into the
Inverter.
Nice when you are on the road for a long time...
