I've had 100 + in the Crew cab. It was OK at best. I prefer having 100 lbs + in a true external. There is not much of a comparison to me. IMO for big loads, an external that functions like an external is as good as it gets.
The CrewCab isn't representative of all the NICE bags. Try the 6500 or the 3600 Metcalf (new). Based on the requirements the guy gave I'd pick the Metcalf.
