I nearly pissed myself at those tents on the back of the Pick-ups, Blind-IO. They look ike such bodge jobs.
I will concede that trucks/pick-ups can be reasonable alternatives to other vehicles for certain things. I will say though that most of the time Americans drive trucks for no reason whatsoever, very much the same people drive 4x4/SUV's for no reason.
From expience I can say that those "bodge job" tents are far more comfortable than ones on the ground. They are drier in storms, don't pull the stakes up in the wind and have the solid walls of the truck bed to reinforce the tent. Also, you don't have bugs crawling into your boots at night.
I would conclude that you know precisely dick about why Americans drive the cars they do. You have clearly never seen a winter in the US. We measure snow by the foot, not the inch. It's easy to promote an estate from your comfortable island sitting in the Gulf Stream, but those of us who call the Rocky Mountains our home know better. Even four wheel drive cars become immobilized by the sheer quantity of snow. Last time I was home we had a storm that lasted 4 days and took us from the driest November on record to the wettest - in the last week of the month. My family was sleeping in shifts to keep up with the snowfall so we would not get shut in. I used to drive an estate, a Volvo 245 DL, it was not uncommon for the only visible part of the car to be the radio antenna following a winter storm.
Also, people tend to visit local lakes and trailer their boats. This means towing, capacity for 2-4 people and room for camping gear and boat fuel. What better vehicle than a 4 door truck?
It's true that many trucks are 2WD, but not where I am from. Most places in the "snow belt" are dominated by 4WD models.
Before you start slinging stones about someone's choice in vehicles, why don't you take a closer look at the need that vehicle is fulfilling? It's easy to mock somene for being different than you, but harder to understand why, harder still is the ability to embrace diversity.
Sweet Eris, and people think Americans are xenophobic.
