I have a 2011 3.6L LaredoX. The gas cap is a yellow cap with e85 noted on it but I don't see anything else on the vehicle. I've tried the manual but it didn't say anything for my model. I'm thinking the previous owners might have replaced the gas cap, but I thought I'd asked.

Yes you're 2011 is rated flex fuel. While I think the 3.6's mechanicals are nearly identical from 11-15 which would make them all capable of running e85, I've read but never truly confirmed that '12 and up differed on the software end and don't have the rating.. E85 will vastly improve the jeeps performance and fuel efficiency. You'll likely be very upset they don't make e100 available as I was today when I filled up today, April 1st.

Agreed.
Engineer and mathematician here, though I work in IT. :)
I ran some calculations one day just for grins figuring out the average reported MPG loss using E85 and versus the cost of the fuel....

I don't remember exactly....
But the fuel would have to be considerably cheaper than 'regular' fuel to make it worth your money. With today's low gas prices, E85 just isn't worth it unless maybe it was selling for less than have of normal fuel.

When I was at Newark Assembly when the Corsair (2-plug-per-cylinder) was going into the '08 durango/aspen, one of the powerplant engineers said they could tune that engine to make quite a bit more power on E85 vs E10, but when they did the E85 mileage went from bad to dismal.

Using ethanol in marine applications leads to big problems, non ethanol fuel is all you'll get at the docks. Some small engines and other things don't last on ethanol, weed whackers to generator... Florida is one of the larger users of non ethanol fuel but we still pay crazy prices.
This is at a station at the dock its $.75-$1.00 more. When all fuels where non ethanol the road to dock price spread was less.

Yeah. We use non-ethanol gasoline for our boats.
