Sounds like they're having a hard time alligning it or whoever is doing it is unfamiliar with the fact that it's an AWD All the time, the toe degree of a AWD and a 4x4 (which is RWD until you engage the fronts) is different since the front tires are always pulling forward, so the AWD degree is wider then a normal 4x4.... like this: \---/ sorta speak...........so when the truck is in motion the toe zero themselves to be perfectly alligned going down the road.
This is the case with especially lifted BIG trucks/tires.

At least this is what my offroad shop told me, I have the same size tires and one thing I've learned over the years that I gotta take my rig to only people who know about them (offroad shops), regular allignment shops or just about anything else other than an oil change they know nothing about and it's worthless wasting time and money with them.

That's just my $0.02.
