Guys - Thanks for the replies - it sure has been a lot of work & we're very happy with it (flaws & all).
The work was mostly me & my Wife along w/Dad when he was visiting but on the big heavy stuff like standing poles & trusses frends & family helped. We could not have done it w/o them!
I have chew gurads on all the exposed wood edges whether or not they are PT so there sould not be any concern on chemicals.
The metal stall fronts are from Priefert but I had the red oak milled locally.
I did the welding on the grill dividers between the stalls & will start working on the swinging dividers for a mare/foal stall when the weather gets lousy.
Here's a photo looking down the hall of the barn. You can see more of the stall fronts.
