Drain the black tank first, use your tank flush (factory-installed or clear elbow) to rinse the tank, drain again, =then= drain the grey tank. You should virtually never have leftovers in your hose by doing this. Also, as someone else said, wait until your black tank is at least 1/2 full, or fill it with clear water to that level, before dumping, and never leave it dry. Always put about 5 gallons back in the tank to keep it moist.
I agree with cutting the sewer inlet to about 1" above ground level. Get yourself an elbow rather than trying to bend the hose to fit into the dump. A Slunky is also real handy for supporting the hose from the trailer to the sewer inlet. If you don't know what that is, just Google it.
