After researching several different brands of portable waste tanks and comparing features, I finally settled on the Barker, and I do not believe that I could have made a better choice. I have the 32 gallon model and it did come with pneumatic tires which is a huge plus and I have already had the opportunity to use the tank and it performed as expected!Here is a list of what I like about it and in my opinion the reasons it performs so well.1) The pneumatic tires make it very easy to pull and with the 2 swiveling wheels in front connected to the handle it is very easy to maneuver. I pulled it through gravel with no problem and up a utility trailer ramp with ease.2) The handle is heavy duty metal and strong so you don't have to worry about breaking it and it also attaches and removes by a 'pull pin', a feature that comes in handy when transporting it and you want the handle out of the way. And when storing the tank on it's end the handle will lay flat against the bottom of the tank.3) The inlet has bayonet lugs to attach the sewer hose securely. (no mess)4) The outlet works just like a regular RV outlet. Attach the sewer hose and pull the door valve. (again, no mess)5) It has a combo vent and rinse connection, very easy to rinse.This is a well built, well designed tank! No question about it. Some reviews complain about not having an area to store hoses etc. but in my opinion that is a non issue and easy to work around.
