My TT has the kitchen just ahead of the axles. During the July 4 return trip, a can of beans (amongst other things) escaped from the top shelf, punctured itself on the upside-down boot brush and proceeded to leak sauce up-and-down the area between the kitchen and bathroom.
It make no difference where the kitchen is. How you pack the shelves, make sure the doors are secure and how you drive are the real factors minimizing messes during travel.
