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?

Grey water? This will work just fine. I've used this to empty pools full of muddy water.PumpMod edit to make clickable link.

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.

Most macerator pumps only use a water connection for flushing the pump after emptying the black tank. And for longer stays you could also use the pump for the black tank of course. If the black tank is emptied first and then the grey tank, a rinse usually isn't needed.

I use the pump jdc1 suggested to pump my grey water into a 35 gallon tank in the back of my truck. Have been doing this for many years at state parks.

There is a macerator pump that does not use electricity but only a hose connection to pump and chop the discharge. I suspect this is what the OP is using. To the OP, look into the FloJet 12V macerator which works more like a garbage disposal and uses no water.
