I'm actually looking at 5100s or 6112s now. I'm trying not to do any lift in the rear, just get level. I need to be able to fit in my garage. Probably do 5100s for now on the middle perch, planning on getting Toyo Open Country RTs in a 285/75R18 on factory TRD wheels. I may get a small 1" wheel spacer purely for appearance.
Thanks for the input!
You may find that level won't work out for you as have many TRD Pro owners such as myself. The Pro comes level due to the 2.5" lift up front from the TRDP coilovers (rear leafs are stock) but with a rear canopy and/or any kind of gear load, the rear squats due to the lack of rake. There are lots of threads on this over on various Tundra forums.
For my 'fishing rig' I ended up with 3+ Coachbuilder shackles as a stop-gap until I decide what to do longer term. I'm running a Snugtop in the 'sportsman' version that is reinforced for 500lbs weight rating, Rhino platform, drawers in the back and a winch up front and get about 1" rake until I load it up or tow a raft/driftboat.
