Rear mats and underseat storage on LT Trail Boss

wacnstac · February 8, 2020

Can someone post some pictures of what it is supposed to look like under the rear seat of a LT Trail Boss. Just got mine home from the dealer and not only are the z71 front mats missing, but the rear mat and underseat storage seems to be in dis-array. Maybe that rear underseat storage bucket isn't compatible with the rear z71 TB all weather mats? Mine is just floating around back there and it really doesn't seem to fit where it could be fastened down.

Probably going to be faster to post a photo of your truck and say is this normal etc. Instead of having someone else go outside and take a photo to upload here for you. Also many dealers post photos of interior that might help.

This is what I have. I believe those front floor mats are stock and not what was supposed to some with LT Trail Boss, correct? In the back, I think it might be the correct floor mat but the way it goes all the way to the back prevents the underseat storage from mounting. In fact there is one screw and one carpet screw in it that would have to go through the mat for it to mount. And it doesn't fit properly over the mat anyway. Is the underseat storage wrong? It is just incompatible with the mat? Is there a different underseat box for the rear for this configuration on this truck?

Can anybody help me out? Have to call the dealer today.

I am traveling and can’t offer a pic at the moment, but the front mats are not what came with mine, and the under seat storage is not the same either. Pics of the mat package are on Chevy accessory website.

That is not what is on mine either. I can take real pictures later but here is basically what I have from the accessories page.

Front Mat

Back mat. My under seat rear storage looks like this pic too. I don't have the larger under seat storage that comes out to the edge of the seat.

I bought All Weather Floor Liners for my Elevation and the rear mat had be cut to fit underneath the rear storage box. What you have in the front is the All Weather Floor Mat and not the Liner I believe. Not sure about the rear.

You have to cut part of it off. Don’t need to cut much just cut enough that you can get the standoffs through for the organizer. I have to make the cuts on mine but my neighbors truck (exact same) came with his cut. I will see if I can get a picture of his.

You need to pop holes into the storage and remove the jack holder and move it to the inside of the storage.

Found this thread about the rear mats and the storage box.

That explains my problems in the rear. The dealer was too lazy to trim or even ask me about it. Sort of glad he didn't trim as I might just not use the rear box. Seems kind of dodgy.

The back matts have to be trimmed when you add under-seat storage because in their factory state they come all the way up in the back with that rim that goes around the back.

If you flip the matts over you will see these pre-cut guides or grooves that you can take a utility knife to and easily cut them to fit. Seriously its almost impossible to mess it up if you flip them over.

I think there is even a little scissors symbol on the underside where the groove is that indicates what it is for.

Mat position looks OK to me. Might not want to cut, that lip might be there to keep that POS carpeted unsecured bin from sliding forward in a hard stop.

I reinstalled the cheaper aftermarket from my '16 which fit just fine except for interference with the new location of the jack. Problem solved, unbolted the jack and bolted onto the bottom of the plastic bin .....fit just fine and the anchor brackets secure to the seat bolts just like in the '16. You can store a few hundred pounds of crap in it and it will remain in place in a sudden stop. Plus the high lip seals the entire bucket without the jack cutout so it is waterproof and can store snow covered boots or hold a few gallons of spilled liquid. Might even serve to catch water leaking from the infamous rear window and keep the carpet/jute backing dry in the interim.

Do this. The underseat organizer in my truck does not budge, you can barely lift the front of it to slide part of the mat underneath.

Your front mats are wrong. Id be back at the dealer asking for the correct ones.
