not very familiar with those generators, but make sure you have any needed pigtails/adapters for your shore power cord (I have a 50 amp rig, but my honda twins have a 30 amp plug, so i need that 50 to 30 adapter).
throw in any tools needed to attach paralleling cords (i.e. phillips driver).
keep a bottle of your fuel treatment of choice handy - and NEVER - put gas through them that hasnt been treated unless you are 100% positive it will be burned on that trip.
i also keep a quart of the needed oil and a couple extra plugs (and wrench to change them) in the rig as well.
