Class A Driver Not Driving Truck Everyday

If I'm doing paper logs is the f150 miles counted for the day? - Yes

If I'm driving the f150 and another class b driver is with me are they co drivers? - Dunno, maybe someone else can answer. I would expect not, as the f150 is not likely to be a cmv. i.e. towing a trailer over 10,000 lbs, or the f150 is over 26,000 lbs.

Do the same hours of service apply cause I may drive a class b truck? - Always, but that means you must meet specific criteria to need to log driving i.e. be at the controls of a cmv.. Otherwise it's simply On Duty. It's not Drive time.

Take a 30 min break before 8 hrs is up? - Only if you drive a cmv after the 8 hours.

Only can work 70hrs before I need a 34hr reset? - Again, only if you drive a cmv after the 70. You can work (and drive a non-cmv) for the company for 100 hours straight. Only objection will be your body handling it.
All logging rules only (with one specific exemption of co drivers) limit Driving time. There are no limits to on duty time. And remember, even driving a non cmv is simply on duty. It's not drive time

 

IF you are driving an under 10,000 gvw vehicle with no trailer (for example) you do not log.

If you drive that same vehicle and then you get into a truck, then the time you drove the under 10k vehicle counts as on duty time.

If you do not drive a truck but just the under 10k truck all day, then you do not log it at all, it is off duty.

These are what rules we had to work by when I worked at the temp service. You were subject to the time clock rule, even if you logged in a truck.

Oh as far as the co-driver, it doesn't matter in the under 10k truck.

 

Are you normally driving less than 150 mile radius and back home base every day? If so, you may fall within the local exemption and not have to fill out a log at all.
