If you think about it everything is luxury beyond a tent, sleeping bags, food and water. I'm always struggling with room (and additional weight to an extent) in the truck since we're 3+dog in a small SUV so some items I have to leave behind. Here're things that we do bring with us regardless:
1. 3.5" XL REI inflatable pad for me, 2.5" regulars for the gf and kid.
2. Soft, collapsible XL dog crate
3. Nemo Helio
4. Propane firepit
5. Coleman tent heater
6. 45L IndelB fridge
Things I'd like to bring that I often leave behind:
1. My coleman gas lantern (love the sound!)
2. ARB awning, usually stays home

3. Additional tools (cordless impact gun etc)
4. Hammock, most places don't allow hanging a hammock from a tree
5. Full sized pillows
6. 12v blender for ice-cream shakes
7. Keurig
8. Solar panel
