Hi Tracy! Yes, you can use the Demco Stay-IN-Play DUO # SM99251 on your 2011 Jeep Wrangler while using the exhaust brake on your Chevy 3500. The DUO requires both a brake light signal from the truck, and enough deceleration to activate the Jeep's brakes.
If the exhaust brake on your Chevy activates the brake lights, Demco notes that you may need to adjust the G-Force controller slightly toward the less-sensitive setting when traveling down steep grades. This will keep the exhaust brake from unnecessarily activating the brakes on your Wrangler.
I think you'll be a lot happier with the Stay-IN-Play Duo, and you won't have to set it up each time you tow. If you want the version with the wireless monitor the # DM86VR is also available.
Where are you headed next once you swap out your brake system?

The demco unit work off of brake switch signal. You hit the brake pedal, the demco unit hits the brakes. Unless there is a switch signal going out from the truck during the exhaust brake cycle ( traditionally no) then the demco unit will not apply brakes. I hope this helps.

Hi Tracy. We have towed a Honda CRV over15k miles using the Demco braking system you are interested in. After adjusting the sensitivity a couple of times on the first trip I haven't touched it. After getting a couple of quotes from local RV shops around $900 I did the installation of the brake system, the tow plate and the lighting wiring myself. I think I called eTrailer tech support once or twice to be sure I understood the comprehensive instructions. Cheers, Bob
