Rsi smart cap is better in every way if you compare it to a fiberglass shell. It's a bit expensive but worth it.
Putting it together deffintly takes 2 people and installing it on the truck takes atleast 4.
The only negitives about the smart cap is when it's snowy or icy outside the latches that open and close the windows will freeze shut. I now carry rubbing alcohol in my truck and spray it on the latches to unfreeze them. The last negitive is I wish the front window could fold down to clean the rear truck outside window.
Over all its a great cap and I would buy it again.
