I noticed the OP stated he was getting a ladder installed. Just curious as to why?
I do not believe that the Bullet roof is engineered to walk on
and is why it does not come with a ladder as standard. I might be mistaken as I often am though.
Your generator is more than sized for the job but remember that it is a generator not an inverter generator and it will be loud.
Enough so that it could/will create problems if used near other campers.
There is a great set of videos
on youtube under "Long Long Honeymoon"
They are great to watch, very entertaining and have lots of information for first timers. Even old timers. They are a bit stuck on Airstreams
but I can forgive them that sin as the information is generically applied.
Great looking rig.
