Great build there!
I was going to mention, although I do not have pictures, 36" set can be built for about $10 in supplies at the hardware store.
Get a 6ft 2x8, cut it in half, cut the peices corner to corner then deck it. smaller rigs can get away with deck board for the top, we used 2x6 for the top with larger rigs. Gives you 8"of lift.
