After much research, I bought a Peragon and have regretted it. I had a Mopar fold up on my Gladiator and wish I had opted for one of those again. You do lose some visibility out of the back window, but that was never an issue for me, especially with the rear view camera. My issues with the Peragon are that the mechanism for the trucks to roll up on is kind of flimsy, you lose a lot of space under that area when the unit is up, and there is no insulation on the cover panels, unlike the Mopar unit. That’s a big issue in Arizona, where I live. My Mopar cover was simple, bullet-proof and let me use my entire bed when necessary. I would have returned the Peragon within the return period, but my partner suffered a serious illness that kept me occupied for several months about the time I purchased it. I will say that Peragon’s warranty service is good.
