The vast majority have 4WD. Do they really need it? For most, no, not really.
It is the more is better, bigger is better mentality.
8 years & over 150,000 miles with a 2WD dually here. Could have used 4WD maybe 6 times. Got stuck with trailer a few times. Got out without assistance each time. Got stuck without trailer a few times. Got out each time without asistance then too.
Used brains over brawn each time to get out.
I carry a tow rope in the truck. Never needed it but nice to have. Somebody with 4WD is always nearby & itching to have a reason to use it.
