The fuel tank on the Plus Six ( also on the Plus Four ) holds less than older models. The general rule of thumb is to use a 250 mile target to refuel. That's about the distance to the fuel warning light coming on. Depends on how you drive though!
I have a Plus Four and on a long trip I fill the tank, zero the gauge readout. The gauge shows full for about 100 miles before it starts to drop, similar for the Six, I believe.
There are two types of luggage rack. One just plain and the other with a place to hold the storage bag.The sidescreen bag on the rack is ok if it is the one designed to hold it. If it is then you could strap it in if you want to. I never do and no problems. If no storage slot on the rack then put it behind the seats.
