I thought I was buying a truck, but it's more like a dirt-bike.
Funny you say that - I thought I was buying something of a dirt bike, and I use it more like a truck more often than trails.
I use it to commute to work, with my laptop bag strapped to the back rack (a Nelson Rigg one - pretty slick), and when I get there, I use it all the time to take random rides during lunch break, leaving me with no choice but get food to go and secure them on the rack under a cargo net to bring food home with me.
I've also got a set of Nelson Rigg saddle bags, and all the time I go to my friend's houses, I put the bags on, fill them up with what I'm looking to bring - even gone to a local beach with my kitesurfing gear and a skateboard strapped upside down to the rear rack using just the bags and the cargo net. A whole change of clothes, shoes, skateboard, kiteboard gear - can't do that on most bikes.
I think I've done things like that more often than I've actually gone off-road trail riding
I love the versatility. In fact, I'm building a custom bike out of two Honda CM400's that I acquired - I'm going to build a removable rear rack / bag holder to turn it from something of a show/cruiser into something functional for commuting and carrying like the KLR. Take a little of the KLR functionality to that bike.
