Tents because most camping is outside car access. I do have a big canvas glamping tent for those occasions though. In good temperature that is as good as it gets, cold can be dealt with, but if too hot I would prefer something with AC. On the other extreme is an ultralight hiking tent. But most usage by far gets something I would consider a base camp backpacking tent - something big enough to not get mad if raining for days, but still able to carry for an hour or two on foot. Hammock gets no use and will probably sell it. Also if living in the US or North Europe instead of the Mediterranean a motorised camper might be a more appealing proposition, but in the mediterranean region wild camping tends to be severely limited and therefore takes more planning and headache to live out of a van for long.
Since I do fairly long road trips every summer in the western USA, my homebuilt pop-up travel trailer is my second home. I'm remodeing it right now to get handier storage space for food and other supplies. I like to be able to pull into an overnight space after a day of driving, set up in 5 minutes, prepare dinner right away, get cleaned up, and go for a walk. I love the feeling of convenience and security that little trailer provides at night. And as I get older, that foam mattress has become a must for sleeping.
