draining black tanks

I'm deciding in which rhinoflex clear adapter I should get for my Thor. Which is better a 90 or a 45 degree?

I have both, most of the time space is so tight that the 90 degree gives just a little more space off the ground.

Like DocMike said, if you have a Vegas, the outlet is really low and the 90 degree will be more useful. Most travel trailers, 5th wheels and Class A motorhomes have much more ground clearance.

Personally, I have never used that little gizmo and haven't felt the need to have one more thing to store. Your results may vary...
