Yet another alignment question!

[jasonator]

2014 SR5 2WD
Toytec 3" lift
LR adjustable UCA's
33/12.5/20 Open Country RT

Problem: It floats all over the road. The Chevy dealer I bought it from is being reasonable and helping me out by doing a 3rd alignment. However, this time they want me to tell them how to do it.....This will be my last shot.

Current specs are:
________Drivers__Pass.
Camber____.4_____.7
Castor____3.5____3.7
Toe_______.12____.11

I feel like based off of everything I have read, this is a decent alignment. However at highway speeds, there is about 1" of play in the steering wheel and when it begins to drift, I have to turn the wheel quite a bit and if im not careful, overcorrect.....

Any insight is greatly appreciated.

Max the caster first then bring in camber and toe. Then rebalance the wheels.

I would only say more caster if the steering was twitcy, but the float that you're describing seems like you should reduce the caster if you can get your toe closer to zero.

Just got my truck aligned this past Saturday. Rides perfect +80 mph with E-Rated tires. max caster is like shooting for the stars when hitting the moon is more than acceptable. don't get hung up on numbers, focus on ride quality. For my truck, getting the caster degrees to align with the lift height seems to work. When I had a 2 1/2 inch lift, 2.6 caster was ideal. I'm now at 3" and 2.9 is perfect.

Fyi, my 2015 is on its 4th suspension... I'm picky as hell with my ride quality.

What is the tire pressure set at?

I would also shoot for 0* camber and closer to zero on toe. I would also check that every nut and bolt they touched is properly torqued.
