I know I've posted this in utility...which if you're interested in selling your truck then I think posts could go either way. I may be new to this forum, but have lived car free for over 5 years now. Here is my old Worksman 1 speed adaptable and 2 different trailers. The one on the right is decked with rope netting, so it's strong and light. The orange one was great for the nephews until the floorboards got ruined. Behind is a Kona Lava Dome that my wife rides, and the high barred schwinn that I got from a neighbor.
If you really feel you would like to live car free...and are physically capable then do it. I have 2 metal hips, and I ride my trike almost every day. Go for it!
