Have you ever done off-roading or overlanding or been anywhere remote? What you speak of is not a problem for a person who can think a few steps ahead. If you don't know how to put your car in 4WD or perform essential operations, going to remote places isn't for you.
maybe he has but most likely he's old school like it's 1989.
i did the SoCal- Alaska - Tuktoyaktuk - Banff - Glacier - Yellowstone - Grand Teton - SoCal solo last year. one driver, one truck, no manuel (printed or digital).
not ONCE did I need the manual... let me just say that... if you don't have basic knowledge of how things work BEFORE you set off for somewhere remote, you will not be able to fix whatever issues that you encounter in the field. Most of the things are basic knowledge that should be a no brainer.
oil used? it's on the cap.
coolant? buy the Mopar one. Auto parts store should be able to get you exactly what you need.
gear and trans oil? bro, are you really changing gear oil in the middle of nowhere? what is this, youtube field maintenance series? If you're leaking gear oil and trans oil in the field, you have bigger problem to worry about than the fluids leaving the truck.
maintenance interval? again, are you really doing maintenance in the field?
dashboard lights? that should be basic knowledge... unless you've been driving Teslas and this is your first gas/ diesel truck, you should know what each dashboard lights means.
engaging/ disengaging 4wd? if you don't know how, Youtube and practice at home before setting off. It is diabolical to NOT know how to use 4WD and then go get yourself off pavement and then sit there on the trail trying to figure out how to.
fuse size? it is printed on the fuse box cover.
fuse box locations? they are exactly where majority of other vehicles' fuse boxes are and they are impossible to miss.
even then... it's 2025, at the very very least there should be a Noco jumper (they are on sale for Prime Day now), a power bank for phone and tablets in the trucks. dead battery in the middle of nowhere? jump it. if it's electrical gremlin then it is NOT something you can do in the field. better get a tow truck and get it to a shop because if you know how to do things you will not need a manual.
(Sorry Stuart the "You" here is not referring to you specifically lol. i don't want to use "if ONE..." it makes it sound like I'm writing a college essay

)
