Used camper shell

I am looking at a used MPULSE brand camper shell for my 1G. I think it is an off-shoot of A.R.E. (but not sure). Has anyone had any experience with these shells? What do I need to look at when buying a used shell? Thanks for the help guys!

Make sure the shell / canopy / topper was designed for an XtraCab. XtraCabs and Regular Cabs have different profiles at the rear cab wall. A shell designed specifically for a Regular Cab's rear wall profile will leave a noticeable gap. The shell should work fine - it'll just look a little odd.

 

Had an MPulse. Not a bad cap; well made/designed and everything worked. Sold it because it was wedge-style and I hated how it made the truck look. Now I have a flat cap and it's much better.
