Don't worry. You'll get the hang of it. When I was driving for a dsp, it was tough driving the vans. However, I kinda just whipped it around like a crazy person. Lol. Don't follow in my footsteps. Just drive like you're taking a driving test.

The easiest way to drive one of the sprinter van is to think of it as a smaller pickup truck that’s enclosed with the back window blocked , i drove a 18 wheeler otr for 4 years , it was a good job but I never had any family Time and no time with my children so I gave it up for a Amazon delivery job , definitely watch your mirrors and don’t reverse unless necessary the backup camera is not totally accurate, also before moving the vehicle scan the area around the vehicle visually to see if there maybe something that could be backed into that’s not visual in the mirrors. Glad you’re alright.

Did you get fired
