Tom,
Your way of doing things does NOT offend, I love reading how everyone does stuff like this, as I always learn something. A lot of HOW we do this chocking, blocking thing, has to do with our comfort levels, if yours is a 2 inch block, then GO FOR IT! Nothing wrong with that.
(What I want to know is how you managed to get that rig parked and NOT hit the electric pole, from the photo it looks like it is kissing that pole!
