I bet they also have low-rolling-resistance tires on them to eek out a few more miles too.

Yes, there are a lot of reasons why SRW design is better in many applications. They can also reduce weight, thereby increasing payload. They provide much greater width between rear wheel wells, so center aisle can be wider to accommodate larger pallets/loads on floor. On independent suspension (like on most electric vans and pickups) it moves rear wheel hub outward (compared to duallies of same vehicle width), allowing rear halfshafts to have a better angle through full suspension articulation, etc...
For vehicles like a farm or dump truck DRW is fine, but for smaller motorhomes I see little advantage beyond lower cost of using an existing commercial truck chassis.
