DTC Seatback Bunker question

Question for those of you who have the Duluth Trading Company Seatback Bunker:

The website says it’s 56" wide. I have a Maverick and the interior width in my bed is about 54-55". Would it fit in a space narrower than the 56"? The site says the poles telescope - will they go narrow enough to fit my space? I really love the storage solution for my camper and it’s on sale but I don’t want to get something that won’t fit. I’m ok if the fabric slightly wraps but my main concern is the minimum pole length

If it is too wide, what are some other, smaller seatback-style hanging organizers that you’ve used and liked?

Most dont use the pole but rather take it out. You can “tuck” in the sides some too.
