Our gray water tank tends to fill quickly. Having a 30-gallon tote tank gets us through a weekend easily. I'd recommend two people to make the dump station run, one to man the hose and one to lift the tank.

Pros: It will hold almost as much as our gray water tank.
Cons: It does not fully dump due to the design--I'm dreading if I ever have to empty black water tank into this. Also, for this size tank, plastic tires will likely wear out quickly.

This was a great buy! The Barker 30 Gallon Tote Tank worked wonderfully. We just spent several days camping at Chickasaw National Recreation Area and only had water/electric hookups. Our gray water tank was almost full after a few days of camping. The dump station was about half a mile from our campsite which was a concern. I was a little worried about losing a wheel/tire or bending/breaking the tow arm, but I am happy to say that it worked flawlessly. Granted, I only did 5mph while towing it which made the trip seem to take forever.

I also purchased the bobber gage, which also worked great! I really liked knowing when the tank was getting close to being full. This allowed me to close the valve before the tank was too full for the remaining water in the hose to go into the tank.

I am very pleased and it sure beats unhooking the camper to make a run to the dump station.

Not happy with this product at all. It's one of the more expensive blue boys out there. I have only had it for 2 months. It works like advertised, however, it sat on the ground under my 5th wheel and was exposed to the afternoon sun. It expanded, and then the axel popped off, and cannot be reinserted. The tank is very rounded now and won't go back to its original shape. The tank is now useless as I can't roll it on its wheels to the dump station. The instructions did not state anywhere that the valve needs to be open to prevent expansion in the hot sun.

works really well but it would have been nice if you didn't have to buy the other end to connect to your waste water tank

As nasty of a job as toting human waste is, this product gets the job done easily and quickly. I think 22 Gallons is about as big as I would ever go (I'm a female) It is heavy when it's full but it rolls easily and everything with it worked properly! I would recommend it to anyone who needs one!
