Congratulations on the new truck; it looks like a beauty! I would be a bit worried if I could say no after trying out a new one too. :B How does the fuel economy compare to your last truck?
Was it the DPF that you could not get for your 2012? I am still running stock emissions at this point, but there is no emissions testing in my area (for now at least) so I would probably delete if I had issues.
Thank you for your detailed post and experience. I totally agree with a DRW being much more stable when towing after having towed the same trailer with both a SRW and DRW. As long as I have a large fiver I will definitely have a DRW.
