Now which is more reasonable for this 350/3500 truck to be rated to tow...30k or 23k? Again, keep in mind that the truck will not be test going down the hill towing that weight. Funny thing is, most of these 350/3500 DRW trucks were rated at around 23k before J2807 came out.
Although, I would have to ask how many typical people tow 30k in their 350/3500 or how many people hear tow 12k in their 150/1500 trucks? That is what these trucks are J2807 rated for since the standard is so low at 40 mph for SRW and 35 mph for DRW.
The test itself makes little difference if all trucks perform the same tests. Now we can compare. It doesn't matter if the tests represent what YOU will need. I can now compare one truck with another. Its not difficult to derive expected results for your particular needs.
I can pull my 5'er up highway 68 at 50mph. Mine is rather lite at 10K. I can downshift and pull at 65mph easily if I want to redline the engine the entire way. Would that be an accurate test? Again, it makes little difference as long as the conditions are the same for which to compare.
Most here realize that tow ratings are maximums with expected low speeds. Car manufactures also give 0-60mph times. How many people actually do 0-60mph starts on a typical basis? Very few but the times do give a good comparison between vehicles.
