I'm a new owner of a 2018 GMC Sierra 5.3 with 8 speed transmission and I have my first tow coming up with my travel trailer. It was recently suggested to me that when towing I should start off in manual mode 6 and then go to 7 on highway with the tow/haul mode on as well. He stated i'll be impressed with the towing abilities with this setup. I'm sure there are other topics started on this same question, but rather than searching I wanted to get input from everyone here. So give it to me and let me know your thoughts about towing with this configuration. 

 

Thanks in advance for your feedback!

info on trailer but if it is small as travel trailer sounds like I would only worry about tow/haul on steep hills or under heavy loads. other than that just let the truck go.

I agree.  I tow my all steel open car trailer with my race car and about 1K lbs of gear totalling close to 6500lbs with '18 1500 max tow.  I just put it in D with tow/haul mode on let it do its thing.  Very impressed with this platform vs my previous truck which was a 3/4 ton.

I pull a boat regularly ad all I see Tow/Haul mode doing is holding the shifts a little longer to keep the truck in higher RPM's where the power is.
