I wish I could get a ram charger and a van bucket seat alongside each other to compare
Unless you have the van ones already, why not go with the Ramcharger bases? I agree with poorboy regarding the differences in the floor.
The hinge setup on the passenger seat base is simple enough. Even in a regular cab, I could see where it could be helpful to gain access behind the seats (speakers, tools, whatever).
When I had my '76 Club Cab I used RC bases to install bucket seats. I forget the brand import the seats came out of, but I called them 'recarro wannabes' as they were super comfortable and had a multiple adjustments.
The only mods to the truck itself I had to make was to reinforce the floor for the RC base mounts.
