You shouldn't need to worry about overfilling anything. Make sure the gas tank is not to full, letting gas run out the fill cap. probably the best thing you can do is put some weight behind the rear axel such as sand bags to help give you some added traction. The other thing I would consider is how well your brakes will hold you back if you spin out. and how well you can back back out of there if you get in trouble.
I am from Colorado and we have lots of roads like what your picture shows. As kids we spent time seeing how far we could go on those roads. I also spent 25 years on the fire department and responded to several accidents on these kind of roads. Some of them didn't come out to well.
Just my thoughts for what it is worth.
