How are your mirrors? Do you need mirror extensions?
The hitch will have to be adjusted for your vehicle at some point. Not a high priority just to get it home.
How are the brakes, bearings, and tires on the RV?
Once you have it - I recommend you go find a big empty parking lot and spend sometime backing and turning. Bring something to simulate the size of a campsite space (or your driveway). Back into the space from the right and left. Get a visual queue of how far left and right you can turn without hurting the hitch/vehicle/RV.
Bring some grease for the Ball. Metal on Metal is not good. The receiver will gall the Ball if dry.
Also, bring a air pressure gauge. I have seen techs at dealers ignore checking the tires for pressure. You want to set the pressure at the Max on the sidewalls.
Then before leaving, verify that your turn signals and brake lights work. I took delivery of a new TT with a loose wire that prevented the signal and brakes lights from lighting up.
Another item you will need is something to insert into the receiver latch to make sure it stays locked shut. A small padlock, a large metal safety pin, a small bolt with nut, etc.

End of dirt road, no signs in sight, sun going down: I am not lost, just getting ready to go camping.
You will need a couple boards in case your off side to side.I have a small 12" level for leveling up,I lay it in the floor just inside the door so I can see it easily while leveling. Another good item to have is an IR heat gun,so when you stop to fuel up you can go around and check the temp of your wheels/hubs,hopefully to catch a bearing/brake issue before it"s too late.If one wheel/hub is notably hotter than the others you know something is up.
