Around $25,000-$30,000 for a LX570 with 120-200k seems to be a common price point for these, and the best value IMO. Add $5,000 if you want a Toyota instead of a Lexus. But I agree that the Lexus is the superior tow rig (AHC). Get a truck from the south or west and then treat it with woolwax or fluidfilm or whatever twice a winter. Don't be that guy who drags a pristine rust-free cruiser up north only to ruin it!
Maintenance "gotchas" are pretty limited and all the common ones have been mentioned in this thread. Starter is a biotch on this truck, do it pre-emptively on your own schedule FTW.
Also if you're cross-shopping GX460, don't. IMO your old 470 is a better all around vehicle and actually has a better power/weight ratio than the 460. 460 will not be an upgrade for your camper-haulin' family.
