Tonneau Cover for 60-66???

[TR65]

Hey Guys,

I am trying to find a good tonneau for our trucks. I want one for two reasons.
1. Protect my bed wood from sun and rain during daily driving.
2. Improve gas mileage (Tonneau is supposed to give you around 10% improvement due to reduced drag).

I want a soft, no drill, flush mount, tilt up, removable. There are lots of great tonneaus out there that fit the bill but not a one for our trucks that I can find. Does anyone know what the problem is with our trucks? Is it just that there aren't enough of them to make it worth while or some technical problem?

I know I can get a Gaylords hard shell, but they are heavy and expensive.

Does anyone have a good solution for our trucks?

Thanks for any input,

TR
