Hi this probably is a strange question. The location of my vending cart is on a hill. My cart leans towards the rear axle about 4". My cart is very simple it has a grill, steamer, a place to keep soda and a place for cold items (Chilled with ice). I have been looking at leveling trailer articles but I am concerned. People lean against my cart. Could they push it off the leveling blocks? The cart weighs about 600lbs with nothing in it. Once loaded I will guess it weighs about 700lbs maybe a little more. It has foot brakes on the front wheels. If I level it by raising the rear wheels 4" could it slide off the leveling blocks? Any ideas?
