Towing through the Rockies

[RaiderNick]

Anyone out there have a '09, 5.3L, 6AT, 4WD an do any travel trailer towing through the Rockies? I have this setup and want to get an idea of how heavy I can go without really taxing the truck hard when towing a trailer.

Thanks

Hey Nick,
My dad has a 5.3 '09 Sierra that we use to tow a 22' cmapling trailer through the Rockies with a full load of gear in the bed. It worked really well for what we did, we weren't setting speed records, but we had ample power to safely pass. Hope this helps.

In the hills, weight is your killer, not size. Basically the same drag for a 16 footer as a 36 footer. Look for lightweight, aluminum frame.

I had a similiar application (05 F150 4X4 with the 5.4) and my trailer is 8000 pounds. The trailer weight was a KILLER on my truck. I maxed out at 25 mph on the south bound lane of the graqpevine. My max tow rating was around 9200 lbs or so.
I know some people will say that Ford and GM are completely different but remember they are the same class of truck.
I would recommend sticking around 7000 total weight if you will be on steep grades. On flat ground maxing out the truck is OK.

I hope that helps.

Thanks for the advice. I can appreciate 25 mph up the grapevine (I grew up in Visalia, Ca).

That was kind of my figure (7000-7400 total weight).

Any brand or model trailer is very helpful as well.

Thanks in advance.

be careful on I70 around Vail, those grades aren't fun when towing.
