Skipping on the PK and the Invulnerable save kind of hurts, but at the very least you want to give him a Slugga or CCW to get the +1 attack, it's only 1 point.

Red Paint Job is worth the points on each trukk. That extra inch is as good as a mile for setting up assaults.
I also like Rokkits on Trukk's because they're cheaper. I put guns on there not to shoot with them but rather to keep a "weapon destroyed" result turning into immobilized. I figure that if the Trukks are shooting something either the Boyz are disembarked already and are going to assault or the Trukks are about to die. Besides a Trukk with Red Paint Job & a Rokkit over the Big Shoota brings the squad to 178 Points, only one more over your config.

Sweet.

I see the appeal of Stormboyz in a KoS list since it presents a "hoard" target that will keep up with the other stuff. Not a bad choice. It's debatable if you want to drop the Boyz to add Zaagstruk, but he does add a lot to the squad.

No Indirect Fire? It's an AV12/10/10 Tank with a Pie Plate. You want this sucker hidden to shoot I'd think.
And just about everyone is right on the Trukks and buggies not doing a great job of blocking LoS. Skimmers (and speeders in particular) are awesome for seeing over buggy/trukk screens and just hosing fragile trukks & Orks hiding behind them.
Also if this is for the GT's or just a tournament in particular things will be rediculously tough on you if you come up against a Mech Tau or Mech Eldar force. Mech Tau is particularly nasty since Smart Missiles ignore LOS and are murder on hiding trukks. Trust me I know.
