Hi Pete - I found this exchange on Quest:

Hi all, What would be the preferred side for placement of a dry suit dump valve. Should that be right side so that you can operate it when scootering or would that only apply in the case of a manual dump valve? Any other considerations to take into account? Finally what is a better choice Si-Tech or an older style Apeks.

We toyed with the right shoulder so that it could be adjusted while riding a scooter. Personally I found the nonstandard placement more trouble than it was worth. This was particularly true as I had suits with both configurations. I prefer to leave it on the left for uniformity.

What were the issues you found? I am currently diving with the valve on the right shoulder. The one thing I have found us that the hose to the backup reg can sometimes snag on the high profile of the Apeks dump valve.

I found the same regarding the hose catching on the valve. I also found that having suits with different placements became difficult for little gain. Of course I could have changed all my suits but invariably I would end up using a suit with standard placement. Lastly, while swimming I found the adjustment less convenient given the light in the left.
