what does it take to drive a water truck?

i've driven semis otr for almost 20 years and now i'm looking for something local. while waiting for a local driving job i hired on with a temp agency doing general labor. ironically, someone from a construction company called the temp agency to ask if they have anyone who can drive a water truck. i have a cdl and i've glanced at the tanker portion of the cdl manual. it seems pretty easy to get the tanker endorsement. and i think the basic driving part of the job wouldn't be too hard- take curves nice and easy, don't accelerate or brake too fast, etc. but i'm wondering what else is involved. can i walk into the job without any experience and kind of bs my way through or am i likely to make some pretty nasty mistakes? the pay is extremely good and i would hate to turn down the job if there was any chance i could do it. any tips from drivers with water truck experience would be greatly appreciated!

 

thanks guys for the words of wisdom. i'm not sure if i'll just be doing dust control or jetting too, but i can have our office manager ask the lady in charge. the temp work i've been doing is at a construction site so the advice to take things slow and watch what's going on around me really makes sense. there have been a few times when i realized how quickly one wrong move could make things turn really bad. i'll let you know how the job goes...

btw, what's a pto?

 

also, how do you say "thank you" for individual posts?
