Clearly you are young and do not have back problems. I've done the tent, I've done a popup, I've done a travel trailer. This combines the best of all of those, without so much space that you are tempted to start toting too much shit on vacation.
I've cooked over an open flame, and I've dealt with bucketing rain storms, wet wood and soggy bedding. I've tried air mattresses and raised aerobeds, and I have come to accept that
I have opposable thumbs and large frontal lobes, I don't need to suffer 
With a bad back and bad joints, if I want to be out in nature, I need to adjust the environment to suit me, which is why I have my nice 15,000 btu propane stove and tempurpedic mattress topper
