I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for planning purposes only (general sizing and budgeting) and is based on the information provided by you. All loading cases considered are for vertical loads only, no lateral analysis has been completed. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.

Hold on, let me run a few numbers

Expert:  walkereng replied 1 year ago.

You can use a Double 2x10 Douglas Fir (#1 grade) to span your 6'. Put a 1/2" thick piece of plywood in between, glued and screwed.
