To all you detractors who are essentially saying 'forget the ranger, get the F-150, there's more room inside':
I'm 6'1", and relatively lanky. I'm 28 and a bachelor (as in I don't have a family). I enjoy outdoor activities such as mountain biking, sailing and backwoods camping. I bought a Ranger because it's 'right sized' to do all of these activities. Sure, I could fit my bike in the back of my Civic, but I had to remove both wheels, lower the back seats of the car, and put the bike in. Forget about carrying more than 2 passengers in that situation. I could have used a bike rack, but in some cases they destroy the look of the car and they're also relatively tedious to use. Fairly often, 6 of us will go off for a day long mountain bike trip. We'll load 6 bikes in the back of my truck, put one passenger in my truck, 3 passengers in another car and off we go. Gasoline costs are amalgamated and split between us. The fuel efficiency of the car balances out the inefficiency of the truck.
When it comes to sailing, I can easily pull my 16' Vanguard sailboat without straining anything. Sure, any car could probably pull my little boat, but with the Ranger I don't even notice the weight. It's also very easy to just throw the sail bags (which are very large and bulky) into the back of the truck (and I've got a few different sets, depending on what conditions are like) instead of trying to stuff them into the back of a car.
Okay, going backwoods camping could really be done out of any vehicle. I have no excuse for that.
In all the time I've had my truck (going on 3 years now) I've only ever carried 3 people a handful of times. And the times that I do, it's only for short trips, and I just use the middle front seat (because it does have a seatbelt). It makes shifting interesting, and it's a little cramped, but it does in a pinch (pun intended). I agree, the back of my quad cab is next to useless for passengers. So much so that I even removed the back seats and I use the area exclusively for storing gear that I want to keep locked up. You know, things such as ratchet straps, my Hi-LIFT jack, my chain winch, tools, things of that nature that become useful. Not once have I wished for more passenger space.
So, you're telling me that instead of buying a relatively inexpensive Ranger, I should have bought a hugely expensive Ford F-150(and the bargain stripper ones don't count, because to get into the 4 door ones you automatically have to pay a premium? Just to have some extra room that I don't want? And some extra comfort that, quite frankly I really don't need? So I have crank windows and manual locks. I don't really care.
But, the biggest advantage to having a truck small truck? When my friends and I go out for a night on the town, I have a pretty good excuse not to take my vehicle and be DD. Oh, sorry, my truck only fits one passenger comfortably, hehe.
