bags???..keepin it true

[lofly'a]

i have this dilemma over putting bags on the front of my project 71. to you guys that have them and drive your truck regularly, how is the alignment maintained on the frontend since the front suspension is now adjustable and everything time air pressure changes so does your frontend geometry. what is the life expectancy of the front tires? has anybody discovered any tricks to maintaining a true alignment setting? if you think about it, as you drive from a cold start, even if the truck is at true alignment, as the air in the bags warm up (from engine/outside heat, friction of movement) then i would think things would start to change, or is this change a negligible effect that would not alter frontend alignment? i live in louisiana where in the summer a plastic gas container with only fumes, will swell up like a balloon and sometimes rupture if exposed to the summer sun too long, to give an example,..............of sorts, and tire pressure has the same expansion (without the explosivity) characteristics after operating for a while :p
