2015 Trd pro hauling/leveling

Hi everyone. I’m in the process of purchasing a 2015 TRD pro which I had been drooling over ever since it was introduced.
Anyway, I do plan on doing some towing with it. Between 4-6000 lb camping trailer.
I’ve read that because the suspension is so compliant and that because the truck sits so level, it does squat a bit more than some would like.
My current tundra has a 3 inch leveling kit in the front with blocks in the rear so that it still has a decent amount of rake.
The question is, can I simply add blocks to the rear or the Trd pro without sacrificing too much suspension?
Any other ideas and experiences with the TRD pro are welcome to be shared. Thanks

I have Firestone airbags on mine and they work great for leveling while towing. I tow around 5,000 lbs.

 

Does the RAS raise the ride height a little. I’d like to add a like rake if I could. Looks like the best option so far but I’d like it to raise the rear end a half inch or so.

 

Yes...
