Grey water pump into portable waste tank

We are going camping in a few weeks in a state park in Colorado. We have been there many times and there are no full hook ups, only electric and we take a portable waste tank that we pull to the dump station. It is actually quite a drive, hilly and has speed bumps to get to the dump station, but it works if you're really carefull.

This year I dont know if the showers will be open when we go or if they are, if we feel comfortable using them. I was thinking about putting the waste tank in the back of the truck and then pump the grey water into it.

The macerator pumps seem to need a water connection and would only generate more waste. Any recommendations for a similar pump that could pump it perhaps 4 feet up into the back of a truck and 25-30 ft distance wise?

Macerator pump does not need a water supply and does not create any create any more waste. It is built to do exactly what you want it do do. It does have a hose connection for washout but I do not think anyone uses it. I just bought one to hook up this year that will pump 50' horizonal distance and 5' vertical distance to dump my black tank. I can run gray on the ground where I stay. Google is your friend' $219.00. Mine pump thru a standard Garden hose.
