I thought about a rooftop tent quite a bit and had I lived in Oz, Africa (snakes), possibly Scotland (right-to-roam) and if I'd been 20 years younger, I might have gone for one. What's ruled it out for me is: extra height (would probably forget), lack of places to use it beyond camp sites, plus (and this is a biggie) all the stuff that goes with camping. I've decided that if I can afford a Grenadier, and I can, I can afford to stay in a decent hotel and have my meals cooked for me. The other thing is - you've parked up, got the tent out, put everything up, then you've got to run an errand to the nearest town. With a normal tent, you just leave the tent, but with the roof top tent you have to pack everything up again, drive off, then you might come back to find someone has nicked your pitch. I suppose it's the full lived-experience we're looking at here, roughing it in the outback, except we don't have much outback in the UK. I've done the roughing it bit and wouldn't knock anyone for enjoying it. I've just had to conclude I'm out of that demographic now, sad but true.
