Re: Enclosed Trailers....

I've only changed the oil every 10k in my truck, but it uses a quart (since new) about every 4-5k. Seems like my buddy with the 06 D is 2x as many oil changes as I am doing. I'm sure I would like a Duramax if I owned one.
Just to clarify, what kind of milage would you expect out of a Duramax pulling an enclosed trailer?
Are there any confirmed aero mods with measurable gains on mpg? Even if there were, for the few times a year I pull my trailer, I don't know if there would be a positive ROI.</div></div>
Oil changes are up to the owner's discretion, but my manual says every 3,000 miles for gas engines and every 10,000 miles for the Duramax. There seems to be the same mpg gap between the gas & Dmax when loaded vs. empty (~5mpg) assuming the driving habits are the same...the problem I've noticed with our trucks, at least, is that our Dmax powered trucks pull the trailers so effortlessly that we tend to speed more often, which really seems to hurt the mileage because the turbo is moving so much more air.
And like Cumby stated, the newer diesels respond so well to such simple mods as an airbox and/or exhaust...many guys are getting their trucks tuned with EFI-live and seeing low-mid 20s empty. I tried and tried with my 8.1L, and while I loved that truck and it was a *great* truck, it never responded mileage-wise...taking the torque management off was worth the tune, though.
Aero mods...I've heard a camper shell helps, as does a wing to get the air over the nose of the trailer, or even switching to an "aero" trailer...but I've never tried any of the above.
I'm not sure I understand the part in bold...
