The tri-quad difference

I really don't know what type of truck you are talking about but I can tell you that you need special training to drive LCV's. You can find that reference in FMCSR §380.107. Once you get qualified to operate a Larger Combination Vehicle that's a plus for you when applying at your next job.

 

That's want we call a truck and trailer. Our set up is very similar except we have a drop axle right behind the steers. Our draw bar is longer but the trailer will hold 8000 gallons. The truck will hold 5000 gallons. We don't load that much and keep it to 12,450 gallons.

I don't know why your company spec'd the truck like that because to me there's too much for the weight Unless the last axle on the truck is a tag axle. They could have place a drop axle like we have to better the handling. Ours trucks will go in more places than a semi will because it tracks better. I do not understand why a company or person would look away because you've driven a different set up. To me (and the other drivers where I worked) they handle just about all the same because of the pivot points. You have two at the back of your truck so it's going to go into tighter places than a tractor with the pivot point right behind the cab. BTW that is a LCV. See FMCSR §380.105 and you'll fined the definition and requirements for training.
