Why SRW off road?
This may seem like an obvious question but it’s not to me. Why are srw preferred to drw when getting off the beaten path? Just curious, it is obviously correct from what I have read but I can’t fi...

If nobody's hit on it yet, it's real simple:
SRW cuts two ruts. DRW cuts SIX ruts.
The rear wheels of an SRW will follow right in the path of the front wheels, generally providing less resistance and more assistance as long as there is a bottom.
The rear wheels of the DRW will have to make their own ruts, and squash the rut from the front wheel closed in the process. This takes a LOT more power and causes a LOT more drag.
I had a roommate who was an EMT for a native reservation in rural Canada. Can't remember if he was from Alberta or Saskatchewan, as it's been 20 years since I've seen him. He hated the "mods," the ambulances that were modular units set on DRW van chassis, because of this. A straight SRW van ambulance would go through mud where the "mod" would get stuck.
My own personal experience with this verifies his statement. I tried to forge through the snow with my DRW to bring it up front in late march. Couldn't do it. Even with 4x4. It would hit this snowbank and spin out. My 2WD SRW 1/2 ton walked right through the same snowbank without spinning a wheel.
