Caravans have changed so much...bigger, heavier and way more feature-packed. I have the vehicle to tow with (my Landcruiser) and I love road trips and the outdoors so it makes perfect sense to have one.
It's not for everyone I guess, caravans I mean, but it's a good life, or so I believe, and because I'm in Australia there's enough space and places to go to spend a long time on the road, which is my plan...eventually.
