I also have a 2017 Tundra. I've built it out over the past 8 years to be my ideal western hunting/fishing truck. None of the mods (except skid plates IMO) I've done are "critical" to going hunting, but they definitely offers some ease of mind and comfort. Plus, I really enjoy the researching and wrenching of installing the mods. The truck has gotten me everywhere I want to go.
I do wish I had the longer bed tho, the 5.5ft bed gets quite cramped on longer trips, as you can see in some of the photos
It has:
3" coilover lift and heavy duty leaf springs
decked system
rear tire carrier + full size spare
front steel bumper
steel skid plates
Rock Sliders
Led lights
Bed Canopy
OTT Tune
