Silverado brake controller and hitch pin

[Jack46]

Thanks again Bob. I can already see the mpg improvement over the Suburban. It would get 9-10 hauling and 17-18 on the flats with no tow. In fact I mentioned the Ouray to Durango highway. We drove it in 2013 on our way to the Southwest Adventure Caravan. In climbing that hill I burned four gallons in sixteen miles. In some places it was a 15 mph, 1st gear pull. No doubt that Duramax will be an improvement. Hopefully one day we'll see you "down the road" Jack

These trucks are beasts! I love it! This is how towing should be. It's a blast to pass 18 wheelers going uphill at 65MPH towing 9-10,000#.
Good Luck!

For a long time, I towed at 60 to 62. Then, one time, I was in a hurry and increased to 65. To my amazement, my fuel mileage increased instead of dropping. I now tow at 64 to 65. I get about 14 mpg towing my Classic 28 on most terrains.

Some of my worst mileage is in the Texas Hill Country where there is an endless series of small but steep ups and downs. I lose more on the upgrades then I gain on the downgrades. I can improve my mileage in these conditions by shifting to "M" and shifting down with the button as soon as I hear the engine start to load on the upgrades without waiting for the transmission to shift down on its own.

Thanks John[/QUOTEGround any one wire from each magnet. Connect the remaining wire from each magnet to the blue wire. The magnets will then be in parallel, just as they would be on a single axle drum brake trailer. It doesn't matter which wire you choose.

My 2007 3/4 silverado w 25' safari is set at 7. Seems to work fine, set up according to the manual.

I tow my 30FC with a 2014 GMC Sierra HD. Looks like I am in the minority here on two fronts: I set the brake gain to 10. And I use the Tow/Haul mode with the exhaust brake on when towing. They seem to work well together. Our trip last summer was to Santa Fe, then Mesa Verde, then up to middle Colorado, and then back east through Denver, Nebraska, etc. Towing was a pleasure with the Duramax Diesel.

For a hitch lock I use a 5/8 lock from Bolt Lock, keyed to the truck key.

I believe the OP uses a Hensley. I also have a Hensley and after I got the GMC truck as TV, I switched the Hensley bars from 1400 lb bars to 1000 bars.
