No - with respect to board length --- the stack I use starts with a 4'-6" long board, with each succeeding board shortened by 4" overall, and centered on the board below (---creating a ramp on either end of the stack) until the top board remains long enough to fully support both axles when the trailer is centered on the stack. Again, I use four boards and - when on a hard surface - three boards will generally raise the suspended axle enough to clear the ground. I also beveled the top ends of the boards about 1" on a 45% slope to ease the ramp slightly. The trailer easily climbs the ramp and, if it were much shallower, it would be difficult to "suspend" one axle for service (---lack of clearance!) I carry the stack "made up" across the rearmost end of my pickup bed, strapped in place using nylon cargo straps - but your transport configuration will probably vary. The remaining detail I used for the "pegs" consists of 1/4" diameter x 1 1/2" long galvanized lag bolts screwed into the bottom of each upper board, with a stack of washers fitted on each bolt to produce a peg about 3/4" long. I used 4 pegs per board with the matching female holes drilled in the top of the lower board. That way there's nothing sticking up when you use only two or three boards. The bottom board doesn't have pegs and the top board doesn't have holes. A coat of paint keeps the boards in good shape when they have to stay out in the rain and mud! The long length of the stack actually makes getting the trailer up on the boards fairly easy since lining the boards up parallel to the side of the trailer with the stack positioned on the tire is a piece of cake. The only tricky part is placing the stack where you want the trailer to stop - either by backing it on or pulling it ahead.
