Greater efficiency is at your fingertips when you simply engage the Tow Haul mode. The weight of any E-450 is sufficient to justify the use of TH even if you are not towing... you are hauling 14,500#. Now put the money you just saved into a fund for any unforeseen repairs that may be coming down the road.
As always... Opinions and YMMV.
:C
Tow Haul Mode activated causes RPM to go up considerably. I don't see how that could save fuel. But do enlighten me please.
I "pay" myself mileage so there is always a ready repair fund.
Fully loaded (all tanks full and 2 folks with their belongings) I come in at 13750 lbs.
Try rereading my post... I did NOT say using Tow Haul will improve your mileage. :S That is not its function but in the course of making your drive train more efficient you will in some circumstances actually get better mileage than without it.
Amount other things using TH reduces your trans fluid temperatures significantly contributing to overall efficiency and again, sometimes better mileage. If you are not using TH you are slowly but surely cooking your transmission needlessly.
Since everyone loads differently it only makes sense to use the GVWR of the E-450 {14,500#} for the purposes of this discussion. Most E-450 class C's and virtually all of them over 30 run very close, if not over that number due to their inherent lack of payload. Oh and I do have to ask, why one earth would you run "fully loaded {all tanks full...} ??? Do you enjoy hauling full black and grey tanks? :h
:C
