owner/operator salary

I know you've said that there are a lot of variables with owner/operator salary, however, could you estimate how much a team (a couple) owner/operator driving flatbed basically from coast to coast would make, especially with gas prices the way they are. (would the salary be total, for the team, or per person?) How much would that translate into month-to-month, in case the couple would want to take off work for a month? Thanks!
