Correct 110v ga wire to camper


Reposting,, I'm new and posted original post on wrong thread.

Currently running 350' of 12 gauge extension cords to camper. Most everything is 12v but we do run the microwave and coffee pot occasionally. I know we're pushing the load on the wire and plan to do one of two options. Go with 10ga (aluminum) underground to trailer or maybe move to a better site but that pushes the length out to 450'. Will the 10ga be enough for either application?
Thanks

You will not find aluminum conductors that small. Also a #10 aluminum would only be good for 20 amps.

Using the Southwire voltage drop calculator you would need #2 copper for a distance of 400 foot to keep voltage drop under 3%.

At that distance, solar may be a decent option as long as you don't use the microwave and coffee pot very often.
