Hello, just bought first rv. A small pop-up. Only have a 10 gal fresh water tank and kitchen sink. I have a fitting on the outside to hook a hose to run out the drain water from the sink. Being a newbie, I am wondering what is the best thing to do. I have seen portable storage tanks that you roll to the dump station, but I do not even know how the dump station operates. Am I going to have to lift that big tank up or is there a hole in the ground? Hate sounding so dumb but I didn't want to buy some tank that I can't lift if I need to. The dealer I bought the RV from said to just run a hose into a 5 gallon bucket. Is that acceptable? Thanks
