The material is molded to fit but not that thick, sound deadening (I used Kilmat) is a must for sound and insulation. Big difference in sound, rain, and music. Love it, recommended.
Get what you want and are going to Use.
What are the Offroad characteristics do you want?
I went with the Overland because I wanted a nice (better inside) convertible Truck and turned it into a Overcon.
Plenty of clearance, I didnāt want to go all the way to the edge with the Killmat but I think you can, fit is really good, had to cut out some of the holes (not stamped out) and one of the emblems poorly sewn.
Happy with the look, sound and final outcome ?
