First of all, welcome to the Forum.
Now for the bad news.........
That trailer will probably be 8000# once loaded up with battery, propane, some water, all your bedding, clothes, kitchen stuff, food, drink, tools etc.
And that 7650# max trailer weight gets reduced by everything over 150# in the truck.
PLUS you are looking at a loaded tongue weight over 1000#, maybe as much as 1200#.
I suspect you are going to run out of payload rating real fast and possibly exceed your hitch ratings.
Bottom line - you will not be near your max, you will probably be well over it.
Not a good match IMHO.
