Alpha Systems (VB28547W 28" x 54" x 7" Fresh Water Tank - 45 Gallon Capacity

I've had this tank for almost a year now, it's a well built fresh water tank. I guess I only have one problem with it, my trailer is really low and I need all the clearance I can get, this tank is the perfect size except there is a small section on the bottom that hangs down about two inches lower than the rest of the tank. It's basically a low point for the water pickup tube, which is a good thing in the sense that you'll be able to use nearly all the water in the tank, but it is deeper than necessary in my opinion. Otherwise, it would be perfect.It also includes studs for level sensors, I used the SeeLevel Monitor, but you can see the sensors in my picture and also the low point of the tank...

Tank is thinner than factory Rv tanks, but all of the connections and sensors are in place. Like others have posted the only odd thing is how low the drain port is. I had to elevate the tank on a frame to make room for the drop drain, but I will admit when install that way the tank drains super fast compared to factory tanks.

great tank
