Black and Grey water dumping.
Dunno how far it is to "pull it up front"
This is handy, no matter where you are with your RV.
Get a Macerator (runs on 12VDC
Put a piece of tank hose with fitting (like you would with a normal hookup)
Get an industrial grade water hose. 3/4" but preferable a 1".
Make it 100' or 200' or 300' or 400' or so on.
Run the hose to the place you're going to put the poop.
with the macerator hooked to your tank and the hose run where desired,
open your valve, attach a 12dc jumper battery and hear the gurgle gurgle, whur-whur and watch your tank get empty. (FASTLY).

Hope this helps some.
