Well i just bought my first FR Flagstaff 27HWSC Pop up. It is amazing what they can do with a pop-up these days. I have so many questions. I will start with only one: During my walk thru today the dealer mentioned to me that i should empty the waste tank after 3-4 times of being used? I realize the tanks are small on pop-ups but that seems really small. Does anyone have a good estimate on how long you can go before the black water would need emptied (based on average use between 3 people). I could probably find this out with my own experiments, but i thought i would save a little time.
Thank you everyone.

Ronnie, Denver CO

I am not familiar with the size of the waste tanks on pop-ups, so how much capacity does it have? Secondly, do you have both gray and black water on it or only one? We have a 30 gallon black tank on our Flagstaff travel trailer and I have to dump it once during a week long trip with two people so your dealer's estimate may be right. We have two 25 gallon gray tanks and the one for the shower/bath has to be dumped every other day.

Hello and welcome. Congrats on your purchase. I love popups, and have previously owned one. We didn't have the the toilet option, we used a separate portable potty. I would suspect they would be near the same in size. We got a whole lot more uses than that before it needed to be emptied.
Not sure if they are the same, but you will only find out by trial & error!
Take care.
