Tanker v dry van

I’m a baby driver for Schneider (they don’t train worth a damn) and I currently do dry dock. Been on my own for 2.5 weeks and I am on the struggle bus with backing into spots when I don’t have room for that oh so perfect 45 angle. I plan on getting my hazmat and tanker endorsement asap and want to move to driving tankers in my career. So my question: is tanker actually any better than dry van or is it same shit different looking trailer?

Side note but potentially more important: what’s this board’s opinion on the actual best videos to watch on learning how to back these things in the real world? Thanks in advance.
