Not much more to say except that only you know your time and fitness limits. If you question your ability to round-trip it, experiment a bit to see where your comfort level lies. Maybe drive your truck to work on the weekend and ride home. Then, Monday, ride in to work, and drive the truck home.

Or, figure out ways to bail if it is just too exhausting one day. Do you have a coworker that lives decently close that you could snag a ride with if needed, or an SO who would be willing to come get you if a day beats you up?

Good luck!
