I used a more modern drivetrain in the restoration, my Meral camper has/accommodates 32 mm tires which are sweet spot for combined gravel and pavement.

It has been rediscovered by millennials who have no interest in things that were perfected before the microchip, so you see modern bikes for camping with frame bags that hinder the rider’s knees and can’t really accommodate anything and gigantic seat bags that look like they were designed for a baguette delivery service....
