All 4 of my vehicles are 4WD or AWD. For the vast majority of driving RWD is great thus the selectable-disconnectible transfer case equipped vehicles. My wife's DD is a Subaru Outback wagon and it drives great and is reasonably economical.
On occasion, better traction under less-than-ideal conditions is necessary and I can switch or take the Subie.
We don't get much snow around here but there is frequent freezing rain and if it does snow, it melts during the day and refreezes at night. We also like to snow ski and travel in the mountains so while not a necessity the majority of the time, with regard to 4WD/AWD I'd rather have it and not need it than need it and not have it.
Another factor that I've considered for years is resale. If you have a pickup for sale, if it's not 4WD you have eliminated half your potential market. Someone looking to buy a good used pickup will look at either 4WD or 2WD while someone looking for a 4WD pickup will not look at any other.
