newbie with AAL vs TSB ?s

Hi Guys,
Newbie here w/ a 09 TRD Sport DC. Had it a few weeks now and time to let the fun begin with mods. just dropped a afe ProDry in and got a few mpg's out of it!

Time for the suspension upgrades. The spring tsb has not been done yet and before I do it I'm curious what would ultimately be better. I will be installing a Leer shell in the near future and will be towing a Evolution E3 popup trailer from time to time. Money aside, what would give me a slight lift and best load/ride quality. the TSB spring or something lke the .toytec AAL? not interested in more than 1.5-2" lift max and I will do the 5100s all around. time is very precious with family/work so I don't want to waste a full day for the dealer to perform the tsb if the toytec or other AAL is better longterm investment.

Thanks for the help - tried searching but way to many threads and I don't have the time to read every one

 

Bump...same question here...

 

TSB springs are basically an AAL lift, since your going from 3 to 4 leaf springs. With either, the ride is better with it loaded with the shell. I would go TSB if it is free and AAL if not. With the TSB, you will be getting new leaf packs.
