I noticed this when I put the new 155" on my sled deck - badly needed reinforcement between the running boards and the rear bumper. I don't recall seeing the this pointed out yet. Pardon if it's a duplicate post.
We saw that when building a bud's, he has always installed long Cat bumpers on his Pros, he is going to leave this one alone. Also, look at the footwell tunnel bracing. It is raised up for more strength.
I haven't read all the Axys threads, but has nobody noticed the SUPER cool tool placement and functions?
