So I'm new to towing and honestly a Mopar guy, so this may be a dumb question for most of you.

I'm driving a Chevy Express van Bus (Im not 100% sure of the year, but I know it has a gutless V6 vortect), for a sumer camp. I load it up with campers there gear and a trailer carrying 5 to 6 canoes. I find it struggles with the weight especially on hills. Beside the steering wheel theres a trailer button but I haven't used it yet because I don't know what it dose.

My questions are really.
what dose that button do?
Can I use it everywhere? (part of the trip is an hour stint on the 401 at 110 kph [68mph] I don't want to damage the engine of trans)
will it help with fule economy?

Any awnsers would be nice.

You will do more damage not using the towing button and then you will using it. It is there for towing. Read the owners manual. You can download one if it's lost.

It changes the tranny shift points to help with bigger loads. I use it on our Tahoe in mountain driving w/o hauling a trailer. Try it and see what you think.
