Springs or Air Bags and/or weight distribution - Shackles or Blocks

I am planning a level/lift only to create some space for tires. However, I also tow once or twice a year, a TT that is pushing the GCWR, not over, but close enough to create some sag. I haul the equivalent of a half cord of wood every couple months as well. I am trying to put the right combination together to accomplish a small lift, 1" to 2" in the rear... 3" in the front, most likely a coil spacer up front to keep the cost down, and was originally looking at blocks in the rear, with air bags (I am aware that air bags do not increase payload... just looking to level out the headlights keep the front end on the ground). However, I am now researching springs, and shackles as well. How do you all tackle problems like these with the fewest number of suspension solutions? Oh, this is on a 2017 1794, with tow package, and no TRD.

 

Heavy Duty Dobinson's leaf packs, Ironman 4x4 greasable shackles and bushings. Use Sumo springs to replace the factory bump stops. If you want a good ride add Bilstein 5160 shocks w/res.
