The only thing I wouldn't like about roof top camping are the inevitable nighttime bathroom needs. The very last thing I would want to have to do is not only have to get dressed but then to have to climb down a ladder in the dark not knowing what might be under foot. I'm 67 and yes I still tent camp almost every single weekend as long as the nighttime temperature is above 35. We have a few different tents depending on the length of our stay and which vehicle we take. I have a Harley Davidson Tent for those weekend rides into the Blue Ridge Mountains or the Outer Banks. We use the motorcycle alot during the Spring, Summer and Fall with quite a few out of state camping trips. We also have a Pathfinder and purchased 1 of those free standing tents that attach to the vehicle but can be zipped up for excursions if we choose. We also have a rather huge for the 2 of us 10 person 3 room tent which is used at least 6 times a year for our 4 to 8 day camping trips as we bring 2 queen sized inflatable mattress with us as for those longer trips we do like our comfort. Camping saves us roughly 100 to as much as 300 a night seeing we don't ever stay at Hotels giving us more pocket money to go see places along the way that charge admission or to eat out instead of cooking at our campsite. If we were younger I'd definitely be wanting a Topper Tent
