I have had them both for over 20 years and a total of over 20, the DRW are not worth the cost, if you drive 90% or above hwy on dry road than they are great. The history of the DRW is 20 years ago you had to by them because they did not make a tire that could carry the weight 3000 lbs +, that the the truck was rated to carry,Now they are 3300 and up.
Pros of the DRW : More stable hwy driving
Cons: Thr DRW will cost more no matter how you look at it{if you like the look of DRW than maybe it can justify the cost}
1 More rotating mass less mileage: increase maintence.
2 Off road use is almost out of the Question. Example When we would dump are tri-axles dump trailers at the landfill ,we got stuck more often,Also we had at $500. 00 per truck per year in tire replacements, Debris would get cot in between the rear tires.
3 I live in MN,the DRW will get stuck on a snowflake. Plowing in most cases you will not get hire,Most of the commercial business known this.
4 The SRW will out pull the DRW: You can place 1500lbs more in the DRW bed
5 Ride:If your looking for ride always get the long bed,DRW & SRW ride about the same except the DRW is more Firm.
6 The SRW will go into spots DRW won"t , Sometimes a inch can be a mile
7 Most of the things mentioned in earlier post.
Everthing being consider buy what you want,Make sure it is a cummins it is more loyal than the others and is more bomber friendly. And when engine repairs a necessary you won"t be stuck with dealer only sh_t & COST. and 24 hour a day parts with most parts.
