I purchased saw horses that were rated at 4000 pounds each. You have to build them out, but they are available on Amazon or Home Depot for the same price.
I built them and placed them under my Lance 855s which weighs about 3000 pounds dry.I have the electric jacks on blocks and just extended enough to make solid contact with them, but the weight is on the saw horses.
I did keep it up 38 inches so the door would be up above any snow fall since I parked it in an area that does not get snow cleared at the local campground.
