New Owner Operator: Is $1.70/Mile good for tractor service in B.C 12000 miles gauranteed

Tractor only you own you pay for trailer rent ? And 3000 miles a week that's awesome but I'm pretty sure no home time so let's go say 12000 a month you gonna pay for diesel around $4400 a month $1100 to $1200 each week and you gonna run 3000 miles a week so $5100 you make take out $1100 diesel you have $4000 after diesel expensive a week $12000 Canadian money a month that's crazy running over the road. . It's not too bad
