airbags and suspension question

I have camburg 3" front lift, bilstein 5160 shocks 2" plus AAL 1". i plan on installing the decked system bed liner @205lbs. plus give or take 200lbs of tools and gear. occasionally tow 12' trailer with lumber/materials/atv's. would i sag in the rear? I have a toner bed liner now which i will remove. I have 7 1/2" space now, i know i could install everything listed above and find out.
just looking for opinions. thank you dennis,

 

You will be fine with the decked system. Probably fine with tools. Here is an easy test - get two 200lb friends, had each 2 beers, have them stand in the bed and measure the sag. Then you will know versus guessing.

Worked well for me to figure out I was happy with my truck's setup.

 

+1 more comment - for the trailer don't know, can't tell. Depends greatly on how you load your trailer which drives the tongue weight. Since that weight is at the far back of the truck it could drive airbags if you have significant tongue weight.

 

i kind of figured that thanks for the replys
