My advice? Don’t bother. Save your money for a different weekend rig. These behemoths take a lot of work to make a fraction as capable as your LC and they’ll never fit down the fun trails anyway. If I could do my Tundra over again I’d leave it 100% stock including tires and use it for work exclusively.
Tundies have their place, more space/capacity for payload even on trails, BUT with the size come disadvantages on trails depending on where you go. East coast.. size is an issue, Colorado/Utah probably less so.
Baselining at 62k miles should be pretty straightforward. Change fluids/filters, brake pads, inspect CVs and ujoints. Tires are probably ready for replacement which seqways into mods.
Mods depend on where you want to go suspension and tire wise. Camping accessories vary by how off grid you want to be.
All terrain tires, sliders and winch will get a tundra most places it "should" be.
That and a heavy right foot and correct mindset get it the rest of the way to the places it shouldn’t.
I live in the big tight woods of the west, and my Tundra goes anywhere I need to. I did however get a white one with a few body blemishes curtesy of the PO so I wouldn’t feel guilty about pinstripes, and can easily polish them out.
Oh, and as for mods, so far I’m just running Bilstei 5100s at the 2” height with 2” in the rear and 35x12.50s. I do have some rub at full lock, but it sure looks good! I might go narrower next time and see if I get away from the rub, but will stay 35” tall.
