OK, OK I braved sub freezing temps to bring you two shots of the stairs going up to the bus and the trestle I made out of full dimensioned hemlock 2x6. I made four braced posts for each corner of the van that are made of three 2x's each with the middle one 5 inches shorter to cradle the van frame. I then strapped the frame onto the barn with seismic tape. This deal rests on three more 2x that span 10 ft and connect to 8x8 hemlock beams...so far so good.
