Any voltage drop in 475ft of 2-2-4 aluminum wire
My cabin is 475 ft from the power meter on my land and I need to run a line to it. Im going to use 2-2-4 aluminum wire and would have an electric stove ,water heater, well pump and a few kitchen appliances as a load, do you think that the 2-2-4 wire will work ok without too much voltage drop?

Even with a modest predicted load of 50A, you still have nearly 6% voltage drop which is too high in my opinion. Code recommends you limit voltage drop to 2% on feeders; however that is not always practical. I think you should at least strive for 5% which would require #2/0 aluminum minimum.
I should also note that voltage drop is not a required design parameter based on the code, so you can use the #2 aluminum for a 100A service at 475', it's just not a good idea to do so. Code only covers safety, not good design practices.

Unforetally with that much distance if you have electric stove , electric water heater on you will really face serious voltage drop.
You will need much larger cable size to handle that kind of load typically like 2/0 may squeak by. but better use 3/0 alum wire or larger if you can get ahold of it in the big box store otherwise electrical supply centre will have much larger one on hand.
