Not a bad idea for the oil pan however Iím gonna try my best to have to get away from the dump. Thank you
Not sure how legally your gonna get away from a dump somewhere... even gray water is not allowed to be dumped at a regulated campsite... now if you are just rinsing your hands off with clear water with bio-degradable soap, then I suppose disposal of a bucket of water somewhere not real near the campsite would pass, but you don't need a sink to accomplish that...
however, if your washing dishes, bathing the baby, or cleaning fish, that gray waste water needs to go to the dump station...
maybe you need something like this portable tank that you can pull to the dump station and then store on the rack on the way home
