And a center stringer is advised for long term durability but really
depends on the load value.


Yes, I'd use either a third stringer, use 2 x 8s, or don't invite fat
people over.

Smile! I was thinking also of an outdoor wheelchair ramp the local
neighborhood built for a friend of mine. I was sort of 'project
manager' I guess. We did it all with donations so no go-fund-me used.
It took us months but we managed to make it so at all times, she could
use it. It's 46inches wide on the ramp but the rails make the inner
part 40 inches. Even though a 'ramp' it still uses a support like a
stringer. We had a center one and 7 4x4 posts to support the central
stringer.

Workers replacing hot water heaters and other heavy stuff can use it
safely. Electric wheelchairs will not be a problem. She's not heavy
but her electric wheelchair is. Guessing combined may be 300lbs?
