The differece between SRW and DRW is the weight of the truck and the capacity of the rear tires. On a SRW the tire size is 285/70/17 and the DRW is something like 235/85/17. When you do the math the DRW can have 4 X 3085 LBs or something close to 12000 LBS less reduced capacity as duals, while the SRW are 2 x 3750 LBs for close to 7500 Lbs. If your truck is 3000 LBs on the rear axle empty well you can have a pin weight of 4500 Lbs. I do have a 2500 and find it drives quite well with the trailer on. My friend with a dually finds it so rough that he takes air off the rear tires. I told him I would not get out of the driveway unless I have 75 -80 Lbs in the tires of any truck. I once had a Ranger pulling a heavy 5th wheel trailer and it worked very well until I came to do an emergecy stop that turned the tires on the rear rims.
Micheline is supplying single tires the carry the same loads as duals on transports and they claim the fuel millage and the life of the tires is much better. Single tires run much cooler then duals.
At work we had dual wheel tired trailers that had flats constantly, we replaced the duals with Singles and the repairs/failures stopped.
Looking at the trailer weights, Its 13000 Lbs Empty so 3200 Lbs or more on the pin and if you load the car in the back you will have to load the front water tanks to balance it well. It should be quite the unit for our small car. I tow my 2100 Lbs car behind my Trailer that totals the load to 14000 Lbs and I was hauling that with my 6.5 Chev with 225HP diesel and trailer weight capacity of 8500Lbs.
