Connect Sink Directly to Portable Wastewater Tank

Hi, I'm working out some basic plumbing for a 6x12 cargo trailer --> camper conversion. My only inside water will be for a sink so I wondered if I could connect the sink drain directly to a portable wastewater tank (https://www.etrailer.com/RV-Sewer/Tote-N-Stor/TNS25951.html) with a short RV sewer hose (https://www.etrailer.com/RV-Sewer/Viper/D04-0402.html.) The tank opening looks like it's made to fit one end of the sewer hose, but I'm not sure about connecting the other end to the bottom of the sink, where I have a 1 1/4" threaded strainer. Anyone tried something like this? The tank will be directly below the sink.

Thanks for any guidance you can provide.

    The gray water should not really smell if just dumped out, it will start to smell bad inside a closed container however. I dump mine straight to the ground everywhere. Gray water is not pollution and a thimble full of soap is not bad for anything either. I even dump onto pavement if the water can get out of the way without others around having to deal with it; it does not have any odor. Sink water is mostly water and soap and whatever is on your hands or left on your dinner plate. Clean the cookwear and plates of debris as much as possible as you dont want particles in your sink hose anyway, and this will keep it off the ground.
    In some parks dumping gray water will not be allowed so a bucket under the hose is all that is needed and that bucket has a way of getting disposed of each day.
    A lot of cargo conversions has just a 5 gallon container to collect gray. This is not rocket science. If the container can hold liquid then it can hold gray.


    Sorry about the delay. It's footracing, usually ultras. Trail running. So, I'm either parked in a field at the start/finish or at a nearby campground--whether state park or something else.

    I like the container I got for catching the sink water but I'm not sure about connecting it. The idea above to use a garden hose directly to it is appealing but I'm unsure how to connect the parts. The sink has a (I believe) standard drain with a 1.25-1.5" (my eyes aren't what they once were) connection on the bottom. How do I get from that down to the garden hose--or anything that will connect to my tote-and-go?

    Thanks again to everyone. I've done a lot of figuring out as I go along and this has been a great learning experience.
