Dragging it/banging it/whacking it would be my concern when transitioning curb-ways/driveways/angled sites/some roadways.
I'm just surprised at all the stuff that folks carry.
We Full Timed and EVERYTHING we owned was with us. We'd pull into a site, set up and then watch weekenders set up. It was like a circus clown car...stuff just kept coming out and coming out and coming out. :B
All of our stuff packed up I could open any compartment and see it all.
But hey....your rig...your stuff.
Nice box & sewer storage. New one will fit right in...just concerned about road clearance.
