JTeague,
You win big with that pump! The difference between the plate center & all the way forward is 60hp or more than 120ft-lbs. The #11 will exceed the clutch all the way forward, so in your process for upgrading, the clutch will be needed.
I'd personally NOT do the #10 if you're going to tow. It's low end is way HOT, i. e. EGT. If you're going that high in hp/torque, consider starting with the #8, which is 10hp or so more than the #10, but doesn't have the brutal low end. If you figure the #8 starts out @ 340hp, then slid all the way forward is 400hp. Mine was slid 3/4 of the way forward, probably around 380hp or so. It worked very good for towing the 5'er.
Also, when you're talking that much fuel, you'll need to do something about the turbo to reduce backpressure & EGT. The info below is from TST some time ago, so the prices may not be valid.
The following TST Power Kits are offered for the '96-'98 12 Valve 215 hp Ram
