I've been using my 2001 tundra as my hunting rig for over a decade and it has been mostly stock with exception of better tires and some minor front shock upgrades over the years......it is very capable as it is; just don't be stupid with it.
While I would love a winch, I don't want to have to drop large coin on a bumper and then upgrade the springs to avoid the sag etc. slippery slope. Might just get a hi-lift and some recovery equipment.....for a fraction of the price I would be able to get out of hopefully anything else I could get into.
I find the best mods are the ones you really need, not the ones that a forum is hot on. For example, for me, snorkles look cool to some, but if I have to do a major water crossing deep enough to be a problem, I really ****ed up somewhere. To me it isn't needed for my rig. I drive this thing 225 miles to our cabin and 225 miles back, I need decent on road manners as well.......so that comes into play. Extra lighting is at the top of my list at this point however.....many snowy trips through the mountains with no light.....plus the damn deer and moose on the sides of the roads.
Since I hunt with my 3 bird dogs, I get more excited about gear storage and keeping the pups comfy, fed, and watered than the latest in long travel remote reservoir shocks.
Be honest with what you are going to use your rig for and build what you will use/need. But what the heck do I know, I just roll through 30-50 miles of logging roads Every weekend for 3 months......lol
