This effect will especially be felt if you get a 2005 or later V10 powered motorhome. From 2005 onward Ford mated their V10 truck engine with their superb 5-speed (6 speeds internally) computer controlled TorqShift transmission. Put this transmission into it's Tow/Haul mode and the V10's performance really shines. Tow/Haul mode is meant to be used in V10 powered trucks when a heavy load is being carried .... and since a motorhome is heavily loading the chassis all the time .... many folks just leave their 2005 and later Class C motorhomes in the Tow/Haul mode all the time. Overdrive still works in Tow/Haul mode (plus you get automatic downhill engine braking), so cruising gas mileage is not effected in this mode while enjoying the improved responsivness.
So many people have so many different opinions on this. I always looked at it like you are; an E450 VAN wouldn't really need to run Tow/Haul, but a E450 w/ a house dropped on it would almost certainly constitute HAULING right? Yet so many people only engage Tow/Haul when going up or down hills.
I still don't really get it - I want to leave it in Tow/Haul b/c logically it makes sense to me but so many don't run it there.
