Handling like an 83 Caddy?
Bolt in a 500ci engine? Go back through your stuff and take some out? Or just live with it- being rail trail, at least there shouldn`t be a lot of climing. If it`s too heavy this time, next time you`ll have a better idea what you can do without. Good luck on your trip- I hope you enjoy yourself and be sure to follow 10 wheels` picture instructions!
