I somewhat know what the tow/haul mode button does, but it seems like it's a big part of the problem with killing the mpg, like the truck is constantly running 300 rpms higher, even at idle.
I had a guy mention getting a small utility hoist, but I haven't found anything that wouldn't make it look like a service truck yet.
