Tow/Haul button: what is it for?
Hi all, very noob question. Just purchased my second RV., 2012 24' Class C on E350. The tow/haul button automatically comes on when started. Sales person said to just turn it off. What is it used...

For the record I too own a 2012 24' E-350 Class C that I have logged 35,000+ trouble free miles in over the last 3.5 years...
Anytime you are running anywhere near your GVWR or towing anything, you should have the Tow Haul engaged. Anytime you are descending a long grade you should have the Tow Haul engaged. About the only time you don't need it is when lightly loaded and descending a very slight, 1 or 2 per cent grade or running on dead level terrain and no head wind.
Tow Haul re programs the engines ECM {Electronic control module = co outer}, resetting the shift points, locking up the torque converter which eliminates friction which = needless heat making your transmission run significantly cooler and your rig run much more efficiently.
As you descend long steep grades in TH the engines compression acts to brake the coach and all but eliminating the need for braking and you will not burn a drop of fuel all the way to the bottom of the grade.
TH is probable the least understood and utilized function of any vehicle. Read your owners manual and know that the salesman you dealt with is an idiot.
