I don't do Touring, but I ride often through a State Park just down the way. There I see riders doing tours on all kinds of bikes. Touring, Road, Gravel, even Cruisers and Trikes... They all have more things in common than differences. Some times gear is arranged on the bike or often in a back pack secured between seat and rear wheel. Some have come through on Thousand mile routes and others just for a day camp. Your light gear experiences will be a true gem of knowledge. Personally I would fix up a gravel bike for touring and go from there. Ride Ride Ride... Happy Happy, Joy Joy...
