If you have a toy hauler and using the 'stabilizers'... There is a chance you will bend them when they are exstended.
imo..... leave out the stabilizers and add good scissor jacks. They give much more stability to the unit. 'I use 'quick release' removable brackets on my scissor jacks so that they are not hanging down as I travel down the road.
