Wow. How many times does this question come up? I've owned four trucks so far. All 4X2. Only once or twice in 20+ years did I say "boy, I wish I had a 4X4". Just not worth the extra cost, extra weight, poorer fuel mileage and added height. If I'm towing in snow, I've made a huge wrong turn or misread my calendar. My wife's cousin tows with a Dodge 4X4 and had to completely revamp his trailer suspension because the truck just sat too high for the trailer. I think that covers it.
I guess ya really don't need 4x4 as long as someone near you has 4x4 to pull ya out..
I have never had a 2WD truck so I cannot comment on the values of 2WD.
I have never got stuck or pushed on a truck yet in the last 26 years.
The 4 x 4 trucks have been great value when traded in, offset the extra cost to buy. Here a 2WD truck is rare.
I have to put my truck on 4WD everytime I use the leveling blocks if the TV is on grass.
I have seen so many campers ruin the soil at campsites with their 2WD, that for the good to owners of campground, we should all have 4 x 4.
I used 4WD many times in Florida, all the soil there is so sandy that the trailer will not move unless I have it on 4WD.
Its ok if parked on pavement or concrete, but off it, it just will not move unless the truck is 4WD.
On my land I never go on grass unless I lock the hubs so as not to ruin the sod.
I use my 4 x 4 so often that I leave the hubs locked most of the time, except on long trips.
While towing the RV, I never notice the fuel difference anyway.
Last time coming home from Florida I had the hubs locked all the way and still made more then 11 MPG towing.
