Not too big a deal.
And you do have rear view mirrors - two in fact, one on each side of the truck.
Given the nature of the vehicle, you shouldn't be parking anywhere that requires you to back straight up

As for the earlier posed question of whether the lessor (Penske in this case) can be found liable for any criminal act or civil damage done by the lessee while using their vehicle, a careful review of any vehicle-rental contract will show that they are free from all such liability
that's side view, Steve !, rear view ( IMO) is that mirror in the middle of your windshield, eh ?
How can Penske be free of all liability on a truck they own, when the driver has no insurance ?
