760' 30 amp electrical circuit

Hello, I am running to run a 30 amp circuit about 760 feet from my 200 amp panel to a 30amp RV receptacle. My county follows the 2014 NEC code. I am wondering do I need to account for 3% or 5% voltage drop in the cable size? so either 250MCM or 2/0 Aluminum. Also How would I get such large wires into the 30 amp breaker and 30 amp receptacle? I am guessing I need some sort of splicer/reducer? Here is where I am getting the wire sizing. http://www.paigewire.com/%28X%281%29S%28hut53hmk4sspwdpbpbmutoo5%29%29/pumpWireCalc.aspx?AspxAutoDetectCookieSupport=1 here is the receptacle I am using http://www.homedepot.com/p/GE-30-Amp-Temporary-RV-Power-Outlet-U013P/202307113 Thanks!

That's a pretty expensive run to power an RV.  I'm getting 350 kcmil aluminum or 4/0 copper using 30 amps at 120v with 3% voltage drop.  Voltage drop is less important for things like lights but will matter for motors in a 'fridge or air conditioner.  Are you planning doing this yourself?  Have you considered how much a 1000' spool of wire that big weighs and how you are going handle it?  Digging a trench that long isn't going to be fun either, even with a machine.

Before spending a bunch of money, it might be a good idea to run your plans by a licensed electrician.
