First day out with our new Schwing 39 on Peterbuilt chassis. Love the setup. There is a ton of storage. Not very keen on vibrator being on the underside of the grate. Also the the engine seems to drop RPMs a lot when pumping. Other than that she ran great.

You will learn thats the best place for on the top side some mixer drive with his shut down can back into it just go with it that way.

what type of rear suspension do you have

If it was going to be on the grate at all Ide rather it be on the bottom for sure...but on my 2014  and our 2008 they are mounted on the back side of the hopper which works out great...I don't understand why they switched to mounting them on grate...and as far as suspension I'll look into that. Give me a bit because I'm still new and learning about the trucks.

I would move the vibrator behind the hopper,  should not be too difficult to do
