Hi all, I use yellow Camco jack stands and a couple 2×4 pieces on top for a slip surface on all three jack stands. I park the trailer by the garage and there's a slight downwards slope to where that gravel drive meets up with the road. The rear jacks only need to extend a couple inches, but the front jack extends 12 inches out to the jack stand/2×4 pieces to get to level. Is that too far? Obviously, the less travel the better, but when I back the trailer into the spot, one jack stand and one layer of two 2×4 on top are all that will fit while hooked up.
