Who cares... Get what works for you and be HAPPY... If it's a 4x2, GREAT... It it's a 4x4, GREAT...
See how it works?
Resale value?? Well, that's just a sign of the times and what's on the lot is what is selling... That's just the way it is..
In the end, it's what the public wants and for me, I only use my 4x4 mostly while not towing, but I have used it for backing my TT and other times and I'm glad I had it..
But, it's my daily driver too, so that's another thing to consider too.
If I could afford a dedicated "tow vehicle" for only towing my TT, it would only really need to a 4x2.. But, since that ain't the case, I got a 4x4.. :)
Good luck, Mitch
