I go pretty light. I have had this tent for a few uears and it has been wonderful. I picked it up at REI (return merchandise) for nearly half off and it was almost brand new. As packed, it is about 3lb and it easily fits in my backpacking/overnighter pack with all the other essentials. It sets up and packs up pretty easy. I use a REI branded inflatable mattress pad and an enlightened equipment blanket/sleeping bag. Everything is pretty light but they are quite comfortable. I have camped 38-40F on the mountains and zero complaints with my setup. I have no desire to camp outside when it goes below freezing so I carefully chose what I want to carry.

The TJ forces me to stay disciplined in terms of what I carry. I have contemplated LJ vs TJ many times, but the LJ is still pretty much a 2 person vehicle with extra space. But the TJ has enough space for 2 people + gear, where the LJ shines is basically that there is an extra space for a dog or for some comfort gear and such which can be nice on certain trips.
I am in the same camp as
@rasband .. just can't do the overlander thing. I sometimes carry a small cooler for food on overnight trips and I always have extra water in a 5 gallon can. I also have backpacking alcohol stove in my pack if I get the desire to eat some hot food or coffee in the mornings. Note that I mostly tend to do trips with 1 or 2 nights outside mostly, with usually 1 or 2 other people, and so what I carry may not apply to you. I will say that I have been wanting to do longer trips and that needs more thought and planning.
One of these days I will share photos of how I carry stuff and what I carry.
@rasband I would also like to hear about your gear choices sometime.
