Weight Police
I have never made a comment about the weight police but I thought this may be interesting: First photo was a 41' Toy Hauler with full water tanks and 30 gallon fuel tank for Hauler. Gen...

I probably should not further stir up the DRW advocates, but here goes:
All LB crew cabs turn like aircraft carriers, so that is not a point.
Convenience
I am not a big fan of walking from so far out in the WM parking lot that my space has a different zip code from the store. I understand that the rear fenders are no wider than the tips of the mirrors, but once I got it into a space the only way to get my fat 70 year old stomach past the car next door was by rubbing all the dust off of his rear fender (or mine). PITA
Checking air pressure on the inner, even with a valve extension. Another pain.
Pulling rear wheels for any reason. Don't start!
Dragging extra weight around when I don't need it was not my idea of fun and doubling the unsprung weight on the rear axle actually degrades suspension performance..
Cost
6 tires cost one and a half times as much as 4 tires.
(Also see extra weight above)
And the famous point of "feeling" more stable
First, dual rears were added to pickups with heavy in-bed loads(primarily in the oil fields of the desert Southwest) to copy the pattern of semi tractors to spread the total weight of the rear wheels over twice as much contact area, thus cutting the psi loading in half and reducing bogging down in sand or other loose material.
If you compute (go back to Statics and Dynamics 101) the increased lever arm at the fifth wheel pin, and this is the only force providing resistance against roll-over, is less than two percent. I know you don't believe it because you have "felt" the difference. Go run the numbers.
The psychological difference is all there. The physical difference is slight at best.
Also, my long bed, crew cab, 4-wheel drive, diesel/Allison is more comfortable to drive (loaded or empty) for long days than my dually ever was and that is what I care about.
