Hey gang, my truck has all the towing goodies. Before towing a 5x8 U-Haul trailer (about 5.5' high), I enabled the 'trailer blind spot' option so I could have BLIS. And no, the trailer didn't obstruct the BLIS sensors. Well, as soon as I hooked up the 4-pin connector, dash warning said BLIS was disabled (along with other crap) due to the trailer. So what the hell is that option for? The trailer was narrow enough that it wasn't obstructing the BLIS sensors, so it'd had been nice to have it. Maybe it's for something else, but couldn't find anything to that effect in the manual. Thanks.

on the trailer screen there is a screen you have to get to for each trailer to set up the trailer blis before it will work so it knows how long the trailer is

Is you truck an 18. I can not see it on the app. If not then I pretty sure you don't have BLIS for a trailer.

Second the posts that say you have to go into the trailer tow settings, choose select trailer, choose add new trailer, and set up the U-Haul trailer, including inputting its length. If you don't do that, the truck just disables BLIS.

I did setup the trailer specific BLIS info, but BLIS still remains disabled. Did anyone get it to work? I have a 2018 XLT.

Works like a charm for me. After you get it set up, when you hook up the trailer to the truck, go into Select Trailer and select the trailer you set up. It should work.

I get no conventional trailer selected although the only trailer was setup as a conventional trailer.

In addition to doing the trailer setup process....go to the settings tab and make sure that trailer blind spot is checked. I had this same issue and just discovered this secondary setting today.
