I kind of like option 3 but I don't know how loud a macerator pump is and how quickly it would pump 35 gallons of gray water. The run would probably be about 15' across the sand and then up into the bed of the truck.
"Kind of like option 3"? :h It's a no-brainer, 15' is nothing, I pump 50' with my macerator with ease. How long? ... geez, I dunno, a couple of minutes I suppose ... why does it matter, a couple of minutes is neither here nor there. That aside, if you're talking just grey and never black why use a macerator when any 12 vdc pump will handle the task just as easily. It's no different than using a pump to transfer fresh water from portable containers in the back of my truck to the trailer's fresh water holding tank - essentially the same task. ;)
