Can anyone tell me if there is a down side to having two separate inlets to a grey tank?
My grey tank may very well span the entire width of the bus. It will be placed against the back wall of the rear cargo area.
My shower house (driver's side) and bathroom sink (passenger's side) are almost directly over the tank.
Because they are on opposite sides, I thought it would be easier not to tie the drains together. Two inlets seem easier.
Commode is composting.
My bus has three separate drains which flow directly into the waste water tank through three separate inlets. We've never had an issue with this and I don't see how you would.
Good way to deal with drains on both sides. Only time it might be an issue is if the tank is full and a curve forces water up into the shower or tub. In that case crossing the bus eliminates that problem but makes the drain line slope very shallow.

The straighter the shot going DOWN the better. My father in law had a huge SS tank made for his 4106 when SS was not super expensive by his welding buddy. All pipes drained into it with just one vent on top. Three pipes going in, all as straight down as he could make them. He never had a problem and it worked for 30 years. Only one dump valve to pull. Don't know your layout but straight down is good.
